US 2026 Midterm Elections

What this countdown tracks

Voters will decide control of the 120th Congress on Tuesday, November 3, 2026, with all 435 US House seats, 33 of 100 US Senate seats, and 36 governorships on the ballot. Hundreds of down-ballot races, state legislative chambers, and citizen-initiated ballot measures will also be resolved the same day.

Background

The 2026 midterms are the first federal election since the 2024 Trump–Harris presidential contest and the first test of the 119th Congress's narrow Republican trifecta. In the Senate, Class II seats are up: Republicans are defending roughly 20 of the 33 contested seats, with competitive races expected in North Carolina, Maine, Ohio, and Iowa, while Democrats defend in Georgia, Michigan, and New Hampshire. All 435 House seats stand for election under maps that were redrawn again during 2025 in Ohio, North Carolina, and Louisiana following post-Allen v. Milligan litigation. Thirty-six gubernatorial contests include open seats in California (Newsom term-limited), Florida (DeSantis term-limited), Georgia (Kemp term-limited), Texas, and Ohio. Ballotpedia's tracker lists state and federal candidate filing deadlines stretching from December 2025 in Texas through June 2026 in several states. Historical midterm patterns — the president's party has lost House seats in 19 of 21 midterms since World War II — frame the expectations, and special elections held through 2025 and 2026 will provide early signal on turnout and swing. The 120th Congress will also face the December 2026 expiration of key provisions of the 2017 Tax Cuts and Jobs Act individual-rate reductions, giving any new majority immediate fiscal-policy leverage.

Why the date matters

Federal law (2 U.S.C. § 7 and 3 U.S.C. § 1) fixes federal elections on the Tuesday after the first Monday in November in even-numbered years, which in 2026 falls on November 3. The date is statutory, not discretionary: states must hold US House and Senate elections that day, though primaries and filing deadlines vary widely. Gubernatorial and state legislative calendars in most of the 36 states with governor's races are aligned to the same federal date to consolidate turnout. The Tuesday-after-first-Monday rule, enacted in 1845 for presidential elections and extended to Congress in 1875, was originally designed to give rural voters travel time from church on Sunday and to avoid November 1, All Saints' Day and a traditional accounting settlement date.

What to watch for

• Senate control math: 51-seat threshold and which Class II toss-ups break late.
• House generic-ballot polling in the final 30 days and district-level Cook Political Report shifts.
• Governor pickups in open-seat races, especially California, Florida, Georgia, and Ohio.
• Ballot measures on abortion access, redistricting reform, minimum wage, and ranked-choice voting.
• Post-election certification timelines under the 2022 Electoral Count Reform Act framework for states.
• Turnout differentials among young voters and non-college-educated voters vs. the 2022 baseline.
• Any contested-result litigation in swing Senate or House districts.
• Secretary of State races in Arizona, Georgia, and Nevada that shape 2028 election administration.
• Down-ballot judicial elections in states with contested supreme-court seats.

Historical context

Midterm losses for the president's party have averaged 26 House seats since 1946, with only the 1998 (Clinton) and 2002 (Bush) cycles bucking the trend — and both were driven by exceptional circumstances, the impeachment backlash and the post-9/11 rally effect. Under Donald Trump's first-term midterm in 2018, Republicans lost 40 House seats and the chamber while holding the Senate. A comparable loss in 2026 would hand Democrats the House, although the redrawn maps in North Carolina, Ohio, and Louisiana complicate any direct translation of national vote share to seat counts. Governor races in open-seat states have historically produced the most consequential down-ballot shifts, and 2026's five open-seat governorships in states totaling more than 90 electoral votes will shape the 2028 presidential battleground.
