The 20 Most Competitive House Districts of 2026, by Rater Consensus
The districts most likely to decide the House majority this November, ranked by the combined 2026 ratings of Cook Political Report, Sabato's Crystal Ball, and Inside Elections, updated through Sabato's July 30, 2026 rating changes, with 2024 margins as the tiebreaker.
How this ranking works
This ranking aggregates the three most cited independent race raters, each named and attributed on every entry: the Cook Political Report (ratings as of June 18, 2026, with 18 Toss Ups), Sabato's Crystal Ball at the University of Virginia Center for Politics (map updated through July 30, 2026, with 21 Toss-ups), and Inside Elections with Nathan Gonzales (ratings as of June 25, 2026, with 14 Toss-ups). Ratings were compiled from the raters' published lists as mirrored on 270toWin's rating tables and updated for Sabato's Crystal Ball's July 30, 2026 rating changes.
The consensus score is mechanical: a district earns 3 points per rater that calls it a Toss-up, 2 points for a Tilt rating, and 1 point for a Lean rating. Maximum is 9. Ties inside a score tier are broken by the certified 2024 margin, closest first; Inside Elections documented that the three closest Republican holds of 2024 (IA-1, CO-8, PA-7) were decided by a combined 7,309 votes. The per-district subscores below surface exactly these components: the numeric lean each rater assigned toward a flip, plus the 2024 margin closeness. Where 2026 mid-decade redistricting redrew a district, the 2024 margin is treated as void for tiebreak purposes and the entry says so; among redrawn seats tied on score, flip likelihood in the new lines breaks the tie.
Two honest caveats. First, ratings move; this table is a snapshot updated to July 30, 2026, not a prediction of November. Second, this cycle's map is unusually unstable because several states redrew districts mid-decade, including Florida's new map signed May 4, 2026 and left in effect for 2026 by a May 26 court ruling, plus new maps in Louisiana, Alabama, North Carolina, and Virginia reflected in the raters' updates. The framework pays no attention to which party benefits from any rating. The raters are named so readers can check every claim against the source.
1Iowa 1st (Mariannette Miller-Meeks, R)Republican-held, eastern Iowa9
Toss-up at all three raters: Cook Political Report, Sabato's Crystal Ball, and Inside Elections (June 2026). Miller-Meeks won 2024 by 799 votes, the closest House race any Republican survived that year (Inside Elections, 2025).
The receipts: Miller-Meeks won 2024 by 799 votes, the narrowest surviving Republican margin in the country, and all three raters open 2026 with her seat at Toss-up (Inside Elections, 2025). The seat's tiebreak-winning closeness, decided by a fraction of a point, is why it sits at the top of a thirteen-district group all scoring 9 (Cook Political Report, June 18, 2026).
2Colorado 8th (Gabe Evans, R)Republican-held, north Denver suburbs9
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026). Evans unseated Yadira Caraveo in 2024 by 2,448 votes, 49 percent to 48.2, without reaching a majority (Inside Elections, 2025).
The receipts: Evans unseated Yadira Caraveo in 2024 by 2,448 votes, 49 to 48.2 percent, never clearing a majority in a swing seat all three raters keep at Toss-up (Inside Elections, 2025). CO-8 is the second of the three Republican holds that together totaled 7,309 votes, the documented basis for the majority (Inside Elections, 2025).
3Pennsylvania 7th (Ryan Mackenzie, R)Republican-held, Lehigh Valley9
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026). Mackenzie beat incumbent Susan Wild by 4,062 votes in 2024, 50.5 to 49.5, the third of three Republican holds decided by a combined 7,309 votes (Inside Elections, 2025).
The receipts: Mackenzie unseated incumbent Susan Wild by 4,062 votes, 50.5 to 49.5, the third leg of the 7,309-vote majority Inside Elections documented (Inside Elections, 2025). All three raters keep the Lehigh Valley seat at Toss-up entering 2026 (Cook Political Report, June 18, 2026).
4Pennsylvania 10th (Scott Perry, R)Republican-held, Harrisburg and York9
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026), the third straight cycle Perry has been rated among the most endangered Republicans after a low-single-digit 2024 win (Cook Political Report, June 18, 2026).
The receipts: Perry has been rated among the most endangered Republicans for three straight cycles after a low-single-digit 2024 win, and all three raters again open 2026 at Toss-up (Cook Political Report, June 18, 2026). The Harrisburg-York seat has been a perennial target without ever moving out of the tossup band.
5Pennsylvania 8th (Rob Bresnahan, R)Republican-held, Scranton and Wilkes-Barre9
Now a unanimous Toss-up: Cook Political Report and Inside Elections already rated PA-8 a Toss-up, and Sabato's Crystal Ball moved it from Leans Republican to Toss-up on July 30, 2026, citing a crowded field that includes well-funded Scranton mayor Paige Cognetti (Cook Political Report, June 18, 2026; Inside Elections, June 25, 2026; Sabato's Crystal Ball, July 30, 2026). Bresnahan unseated Matt Cartwright in 2024 by 1.6 points, 195,663 to 189,411, in a district Trump has carried three times (WNEP, 2024; 270toWin, 2026).
The receipts: Bresnahan unseated Matt Cartwright by 6,252 votes, 50.8 to 49.2 percent, in 2024, one of the closest surviving Republican margins in the country (WNEP, 2024). Sabato's Crystal Ball moved PA-8 from Leans Republican to Toss-up on July 30, 2026, making the Scranton and Wilkes-Barre seat a unanimous Toss-up across all three raters and lifting its consensus score to 9 (Sabato's Crystal Ball, July 30, 2026; Cook Political Report, June 18, 2026).
6Arizona 6th (Juan Ciscomani, R)Republican-held, Tucson and southeastern Arizona9
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026). Ciscomani, whom CEL rated among the freshmen exceeding expectations, has never won the seat by a comfortable margin (Cook Political Report, June 18, 2026; 270toWin, 2026).
The receipts: Ciscomani has never won AZ-6 by a comfortable margin, and all three raters keep the Tucson-area seat at Toss-up (Cook Political Report, June 18, 2026). The Center for Effective Lawmaking rated him among the freshmen exceeding expectations, a legislative strength that has not moved the seat out of the tossup column (270toWin, 2026).
7Texas 34th (Vicente Gonzalez, D)Democratic-held, Rio Grande Valley9
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026). Gonzalez beat Mayra Flores in both 2022 and 2024, and the Valley's continued Republican drift keeps all three raters on the fence (Cook Political Report, June 18, 2026; Roll Call, 2025).
The receipts: Gonzalez beat Mayra Flores in both 2022 and 2024, but the Rio Grande Valley's continued Republican drift keeps all three raters at Toss-up, one of only four Democratic-held seats in the top consensus tier (Cook Political Report, June 18, 2026; Roll Call, 2025).
8Wisconsin 3rd (Derrick Van Orden, R)Republican-held, western Wisconsin9
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026) after Van Orden's low-single-digit 2024 re-election in a district Democrats held for decades before 2022 (Cook Political Report, June 18, 2026).
The receipts: Van Orden won re-election by low single digits in 2024 in a seat Democrats held for decades before 2022, and Inside Elections moved WI-3 from Tilt Republican to Toss-up in its June update (Cook Political Report, June 18, 2026; Inside Elections, 2026). All three raters now agree it is a Toss-up.
9Virginia 2nd (Jen Kiggans, R)Republican-held, Hampton Roads9
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026) in a military-heavy seat that has flipped twice since 2018; Kiggans' 2024 margin was mid-single digits (Cook Political Report, June 18, 2026; 270toWin, 2026).
The receipts: VA-2 in Hampton Roads has flipped twice since 2018, and Kiggans held it by mid-single digits in 2024, keeping all three raters at Toss-up (Cook Political Report, June 18, 2026; 270toWin, 2026). Virginia's voter-approved remap adds uncertainty the raters folded into their June updates.
10Michigan 7th (Tom Barrett, R)Republican-held, Lansing9
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026) in the open-seat battleground Barrett won in 2024; both parties treat mid-Michigan as the state's premier House fight (Cook Political Report, June 18, 2026).
The receipts: Barrett won the open MI-7 in 2024, and both parties treat mid-Michigan as the state's premier House fight, with all three raters at Toss-up in June 2026 (Cook Political Report, June 18, 2026). The Lansing-based seat has no partisan lean strong enough to move it off the tossup line.
11New York 17th (Mike Lawler, R)Republican-held, lower Hudson Valley9
Now a unanimous Toss-up: Cook Political Report and Inside Elections already rated NY-17 a Toss-up, and Sabato's Crystal Ball moved it from Leans Republican to Toss-up on July 30, 2026, after a competitive Democratic primary produced challenger Cait Conley (Cook Political Report, June 18, 2026; Inside Elections, June 25, 2026; Sabato's Crystal Ball, July 30, 2026). Lawler holds a Harris-won district and was the Center for Effective Lawmaking's top freshman of the 118th Congress, and he won 2024 by 6.3 points, 52.1 to 45.8 (Cook Political Report, June 18, 2026; CBS News, 2024).
The receipts: Lawler holds a Harris-won Hudson Valley seat and was the Center for Effective Lawmaking's top freshman of the 118th Congress, and all three raters now call NY-17 a Toss-up after Sabato's Crystal Ball moved it from Leans Republican on July 30, 2026 (Cook Political Report, June 18, 2026; Sabato's Crystal Ball, July 30, 2026). His legislative strength has not been enough to move the seat out of the tossup band in a district that leans Democratic at the presidential level.
12Arizona 1st (open, R-held)Republican-held open seat, Scottsdale and north Phoenix9
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026) after incumbent David Schweikert left the race to run for governor, converting a perennially narrow hold into a wide-open contest (Sabato's Crystal Ball, 2026; 270toWin, 2026).
The receipts: David Schweikert left AZ-1 to run for governor, converting a perennially narrow hold into a wide-open contest all three raters call a Toss-up (Sabato's Crystal Ball, 2026; 270toWin, 2026). The open-seat penalty, worth real points in every rater's model, drove the seat into the unanimous tier.
13Florida 25th (Debbie Wasserman Schultz, D)Democratic-held, Broward County, redrawn 20269
Toss-up at Cook, Crystal Ball, and Inside Elections (June 2026) only because Florida's mid-decade map, signed May 4, 2026, redrew the seat to lean Republican; the Cook Political Report described her old district as blown to pieces, and she no longer lives within the new lines (WUSF, June 15, 2026; NBC News, 2026).
The receipts: Florida's mid-decade map, signed May 4, 2026 and left in effect by a May 26 court ruling, redrew Wasserman Schultz's Broward seat into Republican-leaning territory she no longer lives in, projected as part of a 24 to 4 Republican delegation (WUSF, June 15, 2026; NBC News, 2026). The 2024 margin is void for tiebreak here because the lines are weeks old; the competitiveness is entirely map-driven.
14Ohio 9th (Marcy Kaptur, D)Democratic-held, Toledo8
Toss-up at Cook and Crystal Ball, Tilt Republican at Inside Elections (June 2026). Kaptur, the longest serving woman in House history, won her 2024 race by less than one percentage point (CBS News, 2024; 270toWin, 2026).
The receipts: Kaptur, the longest-serving woman in House history, won her 2024 race by under one percentage point, and the raters split: Toss-up at Cook and Crystal Ball, Tilt Republican at Inside Elections (CBS News, 2024; 270toWin, 2026). The 8-point score reflects two Toss-up calls and one Tilt.
15California 22nd (David Valadao, R)Republican-held, Central Valley8
Toss-up at Cook and Crystal Ball, Tilt Republican at Inside Elections (June 2026), in a heavily Latino, Democratic-registration district Valadao has repeatedly held against the fundamentals (Cook Political Report, June 18, 2026).
The receipts: Valadao repeatedly holds a heavily Latino, Democratic-registration Central Valley seat against the fundamentals, and the raters split Toss-up, Toss-up, Tilt Republican in June (Cook Political Report, June 18, 2026; 270toWin, 2026). His durable overperformance is why one rater tilts the seat rather than calling it a full Toss-up.
16Iowa 3rd (Zach Nunn, R)Republican-held, Des Moines8
Toss-up at Cook and Crystal Ball, Tilt Republican at Inside Elections (June 2026), after Nunn's low-single-digit holds in 2022 and 2024 (Cook Political Report, June 18, 2026; 270toWin, 2026).
The receipts: Nunn held IA-3 by low single digits in both 2022 and 2024, and Inside Elections moved the Des Moines seat from Lean to Tilt Republican in June while Cook and Crystal Ball keep it Toss-up (Cook Political Report, June 18, 2026; Inside Elections, 2026). The split produces an 8-point score.
17Washington 3rd (Marie Gluesenkamp Perez, D)Democratic-held, southwest Washington7
Toss-up at Cook and Inside Elections, Leans Democratic at Crystal Ball (June 2026). Gluesenkamp Perez keeps winning a Trump-won district by low single digits, and the raters keep refusing to call it safe (Cook Political Report, June 18, 2026; Sabato's Crystal Ball, June 2026).
The receipts: Gluesenkamp Perez keeps winning a Trump-won district by low single digits, and the raters keep it competitive: Toss-up at Cook and Inside Elections, Leans Democratic at Crystal Ball (Cook Political Report, June 18, 2026; Sabato's Crystal Ball, June 2026). WA-3 is one of only four Democratic-held seats near the top of the table.
18Michigan 10th (open, R-held)Republican-held open seat, Macomb County6
Toss-up at Crystal Ball, Tilt Republican at Inside Elections, Leans Republican at Cook (June 2026), open because incumbent John James is running for governor of Michigan (Sabato's Crystal Ball, 2026; 270toWin, 2026).
The receipts: MI-10 opened when John James left to run for governor, and the raters split across the board: Toss-up at Crystal Ball, Tilt Republican at Inside Elections, Leans Republican at Cook (Sabato's Crystal Ball, 2026; 270toWin, 2026). The open-seat penalty moved it onto the list without producing consensus.
19New Jersey 7th (Tom Kean Jr., R)Republican-held, central New Jersey5
Toss-up at Cook and Tilt Democratic at Inside Elections, the only Republican-held seat a major rater tilted toward Democrats in June 2026; Crystal Ball did not list it among its Toss-ups (Cook Political Report, June 18, 2026; 270toWin, 2026).
The receipts: Inside Elections moved NJ-7 from Toss-up to Tilt Democratic in June, the only Republican-held seat a major rater tilted toward Democrats, while Cook keeps it Toss-up and Crystal Ball leaves it off its Toss-up list (Cook Political Report, June 18, 2026; Inside Elections, 2026). Its consensus score of 5 is the strongest of the four-way tie for the final table slots, on the strength of a full Cook Toss-up and a valid 5.4-point 2024 margin.
20North Carolina 1st (Don Davis, D)Democratic-held, northeastern North Carolina, redrawn 20255
Moved into the competitive tier on July 30, 2026, when Sabato's Crystal Ball shifted NC-1 from Leans Republican to Toss-up; Cook Political Report and Inside Elections both still rate it Leans Republican (Sabato's Crystal Ball, July 30, 2026; Cook Political Report, June 18, 2026; Inside Elections, June 25, 2026). Incumbent Don Davis, widely described as the most vulnerable House Democrat in the country, faces a rematch with Laurie Buckhout in a redrawn seat estimated at Trump plus 11.5 points (270toWin, 2026).
The receipts: Sabato's Crystal Ball moved NC-1 from Leans Republican to Toss-up on July 30, 2026, one of five seats it shifted into the tossup column that day (Sabato's Crystal Ball, July 30, 2026). Redistricting redrew Don Davis into a district Trump carried by about 11.5 points, making him the most exposed Democratic incumbent on the board; Cook and Inside Elections still rate the seat Leans Republican, producing a consensus score of 5 that ties NJ-7, NC-11, and FL-14, and NC-1 takes the final table slot on flip likelihood (Cook Political Report, June 18, 2026; Inside Elections, June 25, 2026).

Toss-up ratings received from the three raters, non-unanimous districts (as of July 30, 2026)
How to read a race rating honestly
Race ratings are expert judgments, not measurements, so this report treats the raters as named sources and aggregates them mechanically. Cook Political Report listed 18 Toss Ups as of June 18, 2026. Sabato's Crystal Ball listed 21 after its July 30, 2026 rating changes. Inside Elections listed 14 as of June 25. Thirteen districts appear on all three lists, and those thirteen fill the top of this table. Where the raters disagree, the disagreement is printed, attributed, and scored, not smoothed over.
The topline stakes: Republicans hold the House 219 to 212 with four vacancies as of early August 2026, per 270toWin's live count. The consensus forecast has about 208 seats at least leaning Democratic, 209 at least leaning Republican, and about 18 in the disputed middle. The twenty districts above are the disputed middle plus its nearest edges. Control of the chamber lives inside this list, and the subscores show how each seat earned its rank: the unanimous 9-point seats carry three Toss-up leans, while the 5-to-8-point seats carry a split the table prints in full.
Just off the list sit the near-misses that could climb onto it by fall: the California seats Adam Gray and Derek Tran won by 187 and 653 votes, now rated Lean or Tilt Democratic at all three shops, plus NC-11 and FL-14, which Sabato's Crystal Ball also moved to Toss-up on July 30, 2026 but which Cook and Inside Elections still rate Leans Republican, leaving them tied at a consensus score of 5 just outside the twenty (Sabato's Crystal Ball, July 30, 2026; Cook Political Report, June 18, 2026).
The 7,309-vote inheritance
The 2026 battlefield was drawn by the 2024 photo finishes. Inside Elections documented that Republicans held the House majority by a combined 7,309 votes across their three closest wins: Mariannette Miller-Meeks by 799 votes in IA-1, Gabe Evans by 2,448 in CO-8, and Ryan Mackenzie by 4,062 in PA-7. All three seats sit at the top of this ranking with unanimous Toss-up ratings and the three highest margin-closeness subscores in the table. A fourth Pennsylvania seat sits just below them: Rob Bresnahan won PA-8 by 6,252 votes, 50.8 to 49.2 percent, and Sabato's Crystal Ball moved that seat to a unanimous Toss-up on July 30, 2026 (WNEP, 2024; Sabato's Crystal Ball, July 30, 2026). The two closest races in the country went the other way: Adam Gray won CA-13 by 187 votes and Derek Tran won CA-45 by 653, and both of those California seats now sit just off this list at Lean or Tilt Democratic (Inside Elections, 2025; 270toWin, 2026). A reader who wants to know whether the 2026 majority is really in play should start with a simple documented fact: five House seats were decided by fewer than 5,000 votes each last cycle.
Redistricting rewrote the board mid-game
This cycle's competitive map cannot be read without the mid-decade redistricting wave. Florida enacted a new congressional map on May 4, 2026, projected by its sponsors to produce a 24 to 4 Republican delegation, and a judge left it in effect for 2026 on May 26; it targets four Democratic incumbents including Debbie Wasserman Schultz, whose Broward-based FL-25 was redrawn into Republican-leaning territory that no longer contains her home (WUSF, June 15, 2026; NBC News, 2026). That is the only reason a seat she previously won comfortably appears at rank 13 with unanimous Toss-up ratings, and it is why Sabato's Crystal Ball moved Kathy Castor's Tampa seat, FL-14, and Don Davis's northeastern North Carolina seat, NC-1, into the tossup column on July 30, 2026 after redistricting left both Democrats in districts Trump carried by about ten points (Sabato's Crystal Ball, July 30, 2026). Crystal Ball's earlier updates likewise folded in new Louisiana and Alabama maps, and its analysts wrote separately that Virginia's voter-approved remap put Democrats on the cusp of 218 seats in the ratings (Sabato's Crystal Ball, 2026). The margins below are real, but several of the district lines under them are weeks or months old, which is why FL-25's margin-closeness subscore is scored as new-map disruption rather than a certified 2024 margin.
How the board moved between January 2025 and July 2026
The raters' first drafts of this cycle looked very different, and the movement is itself evidence. When Cook published its opening 2026 ratings in early 2025, its 18 Toss Ups split evenly: ten Democratic-held seats, including those of Adam Gray, Derek Tran, Jared Golden, Gabe Vasquez, Laura Gillen, Don Davis, Marcy Kaptur, Emilia Sykes, Vicente Gonzalez, and Marie Gluesenkamp Perez, against eight Republican-held seats (The Hill, 2025). By the June 18, 2026 update, the Democratic side of the Toss Up column had collapsed to four seats: FL-25, OH-9, TX-34, and WA-3. Gray, Tran, Vasquez, and Gillen all moved to Lean Democratic; Sykes's and Davis's districts were transformed by new maps; and the Republican-held column grew instead. Attribution matters here, so the numbers are the raters' own: Cook's mid-2026 board shows twelve seats at Leans Democratic against eight at Leans Republican, consistent with the historical pattern of midterm risk concentrating against the president's party (Cook Political Report, June 18, 2026; 270toWin, 2026).
Crystal Ball's June accounting framed the same asymmetry from the other end: of its 16 June Toss-ups, 13 were Republican-held and only 3 Democratic-held, and its published seat count stood at 213 at least leaning Republican to 206 at least leaning Democratic, with the majority riding on the Toss-ups (Sabato's Crystal Ball, June 2026). On July 30, 2026 the same shop moved thirteen House seats and the Ossoff Senate seat toward Democrats, pushing five House districts, including NY-17 and PA-8, into the tossup column and its seat count further toward the opposition party (Sabato's Crystal Ball, July 30, 2026). Inside Elections' harder-nosed 14-district list is smaller but points the same direction, with 11 of its 14 Toss-ups in Republican hands. Three independent shops, three methodologies, one shared finding: the exposed seats this cycle are mostly red.
Open seats and the retirement tax
Three of the twenty are open, and each opening moved the rating against the departing party. David Schweikert's run for governor turned AZ-1 from a perennial narrow hold into a unanimous Toss-up. John James's gubernatorial run did the same to MI-10 at Crystal Ball. Nebraska's 2nd, where Don Bacon's retirement converts the seat Crystal Ball calls the bluest won by a Republican into a seat all three raters push toward Democrats, now sits just off the twenty at a consensus score of 4 after the July 30 changes lifted three other seats above it (Sabato's Crystal Ball, A Flood of Open House Seats, 2026; Sabato's Crystal Ball, July 30, 2026). Incumbency is worth real points in every rater's model, and these districts are paying the tax for losing it. On the other side of the ledger, Democratic-held FL-25, OH-9, TX-34, and WA-3 are the upper-tier seats keeping the minority party's defense from being trivial, and redistricting pushed a fifth Democratic-held seat, Don Davis's NC-1, into the competitive tier on July 30, 2026: fifteen of the twenty most competitive districts are Republican-held (Sabato's Crystal Ball, July 30, 2026).
Where the raters break with each other
The value of aggregating three shops is that the disagreements are informative, not noise. The clearest is NJ-7: Inside Elections tilted the seat toward Democrats in June, Cook kept it a Toss-up, and Crystal Ball did not list it among its Toss-ups at all (Cook Political Report, June 18, 2026; Inside Elections, 2026). NY-17 stopped splitting on July 30, 2026: Sabato's Crystal Ball, which had kept Mike Lawler's seat at Leans Republican on the strength of his record as the top freshman lawmaker of the 118th Congress, moved it to Toss-up to match Cook and Inside Elections, making it unanimous (Sabato's Crystal Ball, July 30, 2026). These are not errors. They are the raters weighting the same facts, incumbency, district lean, and legislative strength, in different proportions.
The scoreboard does not resolve those arguments; it prints them. A district scoring 5 rather than 9 is telling the reader that professional analysts who study these seats full time cannot agree, and the honest move is to say so and attribute each view by name. If that uncertainty is uncomfortable for a reader who wants a clean forecast, the discomfort belongs to the reader, not the data. The thirteen unanimous Toss-ups are where the certainty lives; everything below rank 13 is a documented disagreement.
Certified 2024 margins in the closest races still competitive in 2026
How the House board moved from January 2025 to July 2026
UPDATE (July 30, 2026): Sabato's Crystal Ball made thirteen House rating changes toward Democrats, all in the same direction, and this table reflects the ones that changed a district's consensus score. NY-17 (Lawler) and PA-8 (Bresnahan) moved from Leans Republican to Toss-up, giving each a unanimous three-rater Toss-up and a consensus score of 9; both rise into the top tier. Three more Sabato moves to Toss-up, NC-1 (Davis), NC-11 (Edwards), and FL-14 (Castor), lifted those seats to a consensus score of 5 because Cook Political Report and Inside Elections still rate all three Leans Republican; NC-1, whose incumbent is widely called the most vulnerable House Democrat in the country, enters the table at rank 20 on flip likelihood, while NC-11 and FL-14 sit just off it in the same 5-point tie and Nebraska's 2nd slips to a score of 4 and off the list (Sabato's Crystal Ball, July 30, 2026; Cook Political Report, June 18, 2026; Inside Elections, June 25, 2026).
The most important movement of this cycle is the collapse of the Democratic side of the Toss Up column. Cook's opening 2026 board in early 2025 split its 18 Toss Ups evenly, ten Democratic-held and eight Republican-held (The Hill, 2025). By June 18, 2026, only four Democratic-held seats remained in the Toss Up column, FL-25, OH-9, TX-34, and WA-3, while the Republican-held share grew (Cook Political Report, June 18, 2026). Seats held by Adam Gray, Derek Tran, Gabe Vasquez, and Laura Gillen all moved to Lean Democratic, taking them off the top tier.
Two forces drove that shift, and they are different in kind. The first is the ordinary midterm pattern of exposure concentrating against the president's party, visible in Crystal Ball's June count of 13 Republican-held Toss-ups against 3 Democratic-held and confirmed by its July 30 move of thirteen more House seats toward Democrats (Sabato's Crystal Ball, June 2026; Sabato's Crystal Ball, July 30, 2026). The second is redistricting, which is not about voters at all. Florida's May 4, 2026 map, plus new Louisiana, Alabama, North Carolina, and Virginia lines folded into later updates, moved specific seats onto and off this list for reasons of geography, not opinion; Emilia Sykes's and Don Davis's districts were transformed by new maps, and FL-25 became a Toss-up purely because its lines changed (Sabato's Crystal Ball, 2026; NBC News, 2026).
The rating changes themselves show the churn continuing into the summer. Inside Elections' June update moved PA-8 and WI-3 from Tilt Republican to Toss-up, NJ-7 from Toss-up to Tilt Democratic, and IA-3 from Lean to Tilt Republican, while Cook moved AL-2, MN-1, OH-7, and SC-1 from Safe to Likely Republican and IA-2, MI-4, and NC-11 from Likely to Lean Republican (Inside Elections, 2026; Cook Political Report, June 18, 2026). Then Sabato's Crystal Ball's July 30, 2026 changes moved five seats into the tossup column and shifted eight more toward Democrats. The board is not settling; it is still moving weeks before the fall campaign, which is why this table is dated to July 30, 2026 and labeled a snapshot rather than a forecast.
Toss-up counts by rater (as of July 30, 2026)
What the evidence settles
The evidence settles that the 2026 House majority runs through a small and identifiable set of districts: thirteen seats are rated Toss-up by all three major independent raters after the July 30, 2026 changes, fifteen of the twenty most competitive seats are Republican-held, and the current majority was built on three 2024 wins totaling 7,309 votes. It is also settled that mid-decade redistricting, above all Florida's May 2026 map and the new North Carolina lines, has moved several previously safe seats onto and off this list for reasons that have nothing to do with voter movement.
What remains contested
What remains contested is everything a rating cannot know in the summer: candidate quality in unresolved primaries, litigation still surrounding several new maps, and the size of the historical midterm penalty against the president's party, which the raters weight differently, which is why Cook sees 18 Toss Ups, Crystal Ball 21, and Inside Elections 14. Reasonable raters also disagree on specific seats: Inside Elections tilts NJ-7 toward Democrats while Crystal Ball does not even rate it a Toss-up, and Sabato's Crystal Ball calls NC-1, NC-11, and FL-14 Toss-ups that Cook and Inside Elections still rate Leans Republican. This report ranks the consensus and attributes every disagreement rather than resolving arguments the evidence cannot yet settle.
Questions people ask
Which House districts are most likely to flip in 2026?
Thirteen districts are rated Toss-up by all three major raters as of July 30, 2026: IA-1, CO-8, PA-7, PA-8, PA-10, AZ-6, TX-34, WI-3, VA-2, MI-7, NY-17, AZ-1, and FL-25, after Sabato's Crystal Ball moved NY-17 and PA-8 into the tossup column. Nebraska's 2nd, opened by Don Bacon's retirement, remains the Republican seat all three raters push toward Democrats, though it now sits just off the twenty most competitive on consensus score.
How many seats do Democrats need to win the House in 2026?
Republicans hold the chamber 219 to 212 with four vacancies as of August 2026, so Democrats need a net gain of six seats for 218. The consensus ratings put about 18 seats in the Toss-up middle, so the majority is genuinely in play in both directions.
Why is Debbie Wasserman Schultz's safe Democratic seat suddenly a toss-up?
Florida enacted a mid-decade congressional map on May 4, 2026, that redrew her Broward County district into Republican-leaning territory she no longer lives in. A court left the map in effect for 2026. The competitiveness comes from new lines, not from any change in how her former constituents vote.
Do the three raters ever disagree?
Constantly, and this report scores the disagreement. Cook lists 18 Toss Ups, Crystal Ball 21, Inside Elections 14. NJ-7 is a Cook Toss Up that Inside Elections tilts Democratic and Crystal Ball leaves off its Toss-up list entirely, and Sabato's Crystal Ball rates NC-1, NC-11, and FL-14 Toss-ups that Cook and Inside Elections still call Leans Republican. Every entry above attributes each rating to its rater by name.
How did the House battlefield change from 2025 to 2026?
The Democratic side of the Toss Up column collapsed from ten seats to four between Cook's early-2025 board and its June 18, 2026 update, as seats held by Adam Gray, Derek Tran, and others moved to Lean Democratic. Mid-decade redistricting in Florida, Louisiana, Alabama, North Carolina, and Virginia separately reshuffled which seats are competitive at all, and Sabato's Crystal Ball moved thirteen more House seats toward Democrats on July 30, 2026.
