How a House Special Election Runoff Works: The Majority Rule Behind Georgia 13's Tuesday Ballot

Why a second round exists

A special election fills a vacant House seat for the rest of the current term. Georgia requires a majority. If no candidate wins more than half in the first round, the top two advance to a runoff on a later date (Georgia election law via Ballotpedia, Georgia's 13th Congressional District special election, 2026; National Conference of State Legislatures materials on runoff elections). The second round collapses a multi candidate field into a two person choice.

Georgia's 13th District is the live example this week. Rep. David Scott (D) died on April 22, 2026. The first round on July 28 produced no majority. Marcye Scott, his daughter, finished first with about 46 percent. Former Gwinnett County school board chair Everton Blair Jr. finished second with about 37 percent. Republican Caesar Gonzales took about 8.7 percent and did not advance (Wikipedia, 2026 Georgia's 13th congressional district special election; Atlanta Journal Constitution, August 20, 2026; Ballotpedia). The runoff is Tuesday, August 25.

What the calendar actually prints

House vacancies do not get an appointed interim member the way many Senate vacancies do. The seat stays empty until voters refill it. That is why specials show up on the Clerk of the House vacancy list and why a majority runoff can leave a district without a voting representative for weeks after a first round (Clerk of the House vacancy materials via prior US Political Rank coverage; Atlanta Journal Constitution, August 20, 2026).

In Georgia 13 the winner on August 25 finishes only the remaining months of David Scott's term. The full two year term starting in January 2027 is a separate November contest. State Rep. Jasmine Clark (D) already won the May Democratic primary for that full term and will face Republican Jonathan Chavez in November (Atlanta Journal Constitution, August 20, 2026; Capitol Beat, July 29, 2026). A voter can therefore face three related decisions on one seat in one year: a special first round, a special runoff, and a November general for the next Congress. Those are different instruments on one calendar.

What a House runoff settles, and what it does not

A House special runoff settles who holds the seat until January. It does not settle party control of the chamber by itself when the district is Safe Democratic, as Georgia 13 is in the published ratings used across the cycle (Arnold and Porter August capital snapshot; prior US Political Rank coverage). Adding one Democratic member after a vacancy still matters for daily floor math in a narrow House. It is not the same event as flipping a Toss Up district in November.

Turnout in the July 28 first round was low, near 3.9 percent with roughly 21,000 ballots in published local tallies (Capitol Beat, July 29, 2026). Runoffs often draw even fewer voters. That does not make the result less binding. It does mean the people who show up decide who answers the district phone for the rest of the year. US Political Rank keeps House specials and Senate map ratings on separate ledgers for that reason. For the Senate side of majority runoffs, see the companion explainer on how a Senate primary runoff works.

How Tuesday fits the wider August specials

August 25 is a double date. Georgia finishes its House District 13 special runoff. South Carolina finishes its Republican Senate nomination runoff between Sen. Darline Graham and Rep. Ralph Norman after an August 11 first round in which Graham took 32.7 percent and Norman 24.6 percent without a majority (Charleston City Paper, August 14, 2026; prior US Political Rank coverage). California's 14th District already filled on August 18 when Aisha Wahab defeated Melissa Hernandez 53.1 percent to 46.9 percent (Ballotpedia, California's 14th Congressional District special election, 2026).

Cook's Senate Toss Up board and the House vacancy list are not the same story. The ranking of the 2026 Senate races tracks flip risk for chamber control. A Georgia 13 runoff tracks representation for one district until January. A republic that can print both dates on the same Tuesday is doing ordinary constitutional work. Read each ballot for what it measures. Tuesday decides a House refill and a Senate nomination. November decides the 120th Congress.
