NYT Siena Puts El Sayed Ahead 49 to 44 in Michigan and Pappas Ahead 50 to 45 in New Hampshire

What Thursday night put on the Senate clipboard

The New York Times and Siena University released likely voter Senate surveys fielded September 15 to 22 in three states that sit near the center of the November map. In Michigan, Democrat Abdul El Sayed leads Republican Mike Rogers 49 percent to 44 percent among 605 likely voters, with a margin of sampling error of plus or minus 4.9 percentage points (Siena Research Institute, September 24, 2026; New York Times, September 24, 2026). In New Hampshire, Democrat Chris Pappas leads Republican John E. Sununu 50 percent to 45 percent among about 600 likely voters under the same error band (Siena Research Institute, September 24, 2026). In Maine, Republican Sen. Susan Collins leads Democrat Troy Jackson 49 percent to 46 percent (Siena Research Institute, September 24, 2026).

A separate University of New Hampshire Survey Center poll fielded September 17 to 21 among 1,418 likely general election voters put Pappas ahead of Sununu 50 percent to 42 percent, with a margin of error of plus or minus 2.6 points, reversing an August UNH reading that had Sununu ahead 45 to 43 (Newsweek, September 24, 2026; University of New Hampshire Survey Center via Newsweek, September 24, 2026). Election Day remains November 3. That leaves 39 days on the calendar.

Michigan: a five point lead inside a five point error band

Michigan is an open seat after Sen. Gary Peters declined to seek another term. El Sayed won a close Democratic primary. Rogers is the Republican nominee. The Siena five point edge sits inside the published 4.9 point error band, so the race remains a statistical coin flip on this one instrument even while the Democratic candidate holds the topline (Siena Research Institute, September 24, 2026).

Other recent Michigan reads sit in a tight band. RealClearPolitics averages near publication put El Sayed near 47.5 percent and Rogers near 44.8 percent, about a 2.7 point Democratic edge across the blended window (RealClearPolitics Michigan Senate, September 24, 2026). Suffolk University put El Sayed ahead 47 to 40. InsiderAdvantage had 47 to 45. Emerson had 48 to 46. A co/efficient survey released near the same window showed 45 to 45 (270toWin Michigan Senate poll table, September 24, 2026). Print every instrument. Do not mash them into a prophecy. Our board on 2026 Senate races keeps Michigan on the same ruler as every other named contest.

New Hampshire: two houses, one direction

New Hampshire is an open Democratic seat after Sen. Jeanne Shaheen retired. Cook Political Report rates the contest a Toss Up after moving it from Lean Democrat earlier in the cycle (Boston Globe citing Cook, September 17, 2026; Cook Political Report Senate ratings, September 23, 2026). The Siena 50 to 45 and UNH 50 to 42 readings both put Pappas ahead on Thursday. Aggregators near publication showed Pappas leads in the low to mid single digits across blended averages (270toWin New Hampshire Senate, September 24, 2026).

Times reporting on the Siena wave said New Hampshire voters described more interest in a check on President Donald Trump than in a candidate who supports him (New York Times, September 24, 2026). That is a preference statement inside one survey, not a certified majority. Keep it next to the UNH favorability rows that found both nominees underwater on net favorability while Pappas still led the named ballot (Newsweek, September 24, 2026).

Maine: Collins still leads the state Harris carried

Maine is the awkward receipt on the Democratic ledger. Kamala Harris carried the state by 6.9 points in 2024, yet Collins leads Jackson 49 to 46 in the Siena wave (Siena Research Institute, September 24, 2026; The Conversation citing recent Maine polls, September 25, 2026). Cook still lists Maine among seven Senate Toss Ups alongside Alaska, Iowa, Michigan, New Hampshire, Ohio, and Texas (Cook Political Report, September 23, 2026; Newsweek summarizing Cook toss ups, September 23, 2026).

Democrats need a net of four Senate seats for a working majority because Republicans hold 53 seats and Vice President JD Vance breaks ties (Cook Political Report Jessica Taylor Senate outlook, September 23 to 24, 2026). Holding Michigan and New Hampshire while flipping four Republican held seats is arithmetic, not mood. A Collins lead inside Maine does not erase El Sayed or Pappas leads elsewhere. It does keep the path honest.

What Friday settles and what stays open

Settled from these instruments: El Sayed 49, Rogers 44 in the Times Siena Michigan sample; Pappas 50, Sununu 45 in the Times Siena New Hampshire sample; Collins 49, Jackson 46 in Maine; Pappas 50, Sununu 42 in the UNH New Hampshire sample; Cook Senate Toss Up column still carries seven races; Democrats still need a net of four for Senate control; Election Day is November 3 with 39 days remaining (Siena Research Institute, September 24, 2026; Newsweek, September 24, 2026; Cook Political Report, September 23, 2026).

Still open: whether October samples hold single digit Democratic leads in Michigan and New Hampshire or compress inside the error bands; whether Maine stays with Collins; and whether Cook House moves published Friday change the district by district path while the Senate board remains a true toss up (Cook Political Report Erin Covey House overview, September 25, 2026). America can publish three state Senate polls on a Thursday night, leave a seven race toss up column intact, and still require every clerk to finish the count in 39 days. That is ordinary self government under a hard clock. Print the numbers. Wait for November 3.
