2026 Midterms: What Is at Stake on Nov. 3
Democrats lead polls as the 2026 midterms near: all 435 House seats, 35 Senate seats and 36 governorships are up Nov. 3, with redistricting in play.
WASHINGTON — Sep 29, 2026 — With five weeks until Election Day, the fight for Congress in the 2026 midterms has a clear shape: Democrats lead in national polling and need a net gain of just three House seats, while Republicans hold a Senate map that still favors them. Voters go to the polls on Tuesday, Nov. 3, 2026. This preview lays out what is on the ballot, where the chambers stand today, what history suggests and which unknowns could still change the outcome.
What Is on the Ballot
All 435 House seats, 35 Senate seats and 36 governorships are up on Nov. 3, according to NBC News. Republicans control both chambers. NBC’s tracker shows the House at 219 Republicans and 214 Democrats, with the remaining seats vacant, and 218 needed for a majority. In the Senate, Republicans hold 53 seats and Democrats 47, counting two independents who caucus with them. Because a 50-50 Senate is broken by Vice President JD Vance, Democrats need a net gain of four seats to take control.
NBC’s Decision Desk currently rates 225 House seats as at least leaning Democratic, 202 as at least leaning Republican and eight as toss-ups. In the Senate, its ratings show three toss-ups, including Ohio, where Republican Sen. Jon Husted faces former Sen. Sherrod Brown, and Texas, where Republican Ken Paxton, who beat Sen. John Cornyn in the primary, faces Democrat James Talarico. North Carolina, where Democrat Roy Cooper faces Republican Michael Whatley for an open seat, is rated lean Democratic. Three governorships are toss-ups.
What History Says
The president’s party almost always loses ground in midterms. Gallup’s 2018 analysis found that since 1946 the average loss has been 25 House seats, and that presidents below 50 percent approval saw their parties lose 37 seats on average, compared with 14 for those above 50 percent. Only Bill Clinton in 1998 and George W. Bush in 2002 saw their parties gain, and both had approval ratings above 60 percent. The Senate is less predictable: YouGov notes that in 2018 Democrats won the House but lost Senate seats.
The Polling Picture
Recent numbers point the same direction. The NBC News polling average, published Sept. 25, showed Democrats ahead 52 percent to 43 percent on the generic congressional ballot, adjusted to a likely-voter scale, and Trump’s approval at 39 percent with 59 percent disapproving. A Quinnipiac University poll of 1,032 registered voters, conducted Sept. 24-27 and released Sept. 29, found 51 percent wanting Democrats to win the House and 39 percent wanting Republicans, with Trump at 34 percent approval and 61 percent disapproval. The Economist/YouGov poll of Sept. 25-28 gave Democrats a 16-point edge among likely voters, but only six points among registered voters. The gap between those groups is a reminder that turnout will matter as much as opinion.
Quinnipiac also found independents favoring a Democratic House 54 percent to 30 percent, yet only 22 percent of voters approve of how Democrats in Congress are doing their job, against 26 percent for Republicans in Congress. Both parties are unpopular; the question is which one voters punish. Republicans hope the map can blunt the headwinds. As NBC notes, many key House and Senate contests are in districts and states Trump carried in 2024, some by double digits.
Redistricting Reshapes the House
The unusual feature of 2026 is mid-decade redistricting. The Associated Press reported on Sept. 28 that new House districts are in use in Alabama, California, Florida, Louisiana, North Carolina, Ohio, Tennessee, Texas and Utah, roughly 440 days after Trump urged Republicans to redraw maps. All favor Republicans except California’s and Utah’s, and if they play out as designed Republicans could net up to nine seats, though a strong Democratic year could shrink that. The AP estimates that about one in 10 potential voters nationwide now live in a different district than in 2024, including more than 6.9 million in Texas, over 6.3 million in California and more than 4.5 million in Florida. In Missouri, the Supreme Court ruled three times against using a new Republican-drawn map, so the 2024 map governs; voters will decide the newer map in a Nov. 3 referendum, and a Maryland ballot issue could open the door to further changes before 2028.
Issues, Dates and Unknowns
Quinnipiac found voters trusting Democrats more on health care, the cost of living, the economy and international conflicts, while Trump’s economic approval stood at 31 percent. Cost of living, tariffs, immigration enforcement and the Iran war are the recurring themes. Peter’s World has tracked how the conflict feeds into the campaign in U.S.–Iran escalation raises midterm stakes, and the legal fight over ballot rules in the Supreme Court ruling on mail-in ballot restrictions.
Voting is already under way. The Center for Election Innovation & Research reported as of Sept. 18 that early in-person voting opened Sept. 18 in Idaho, Minnesota, South Dakota and Virginia, most states begin in mid-October, and Kentucky starts Oct. 29. Sixteen states and Washington, D.C., start mail voting in September. Registration deadlines vary by state, so voters should check with their local election officials. The same group noted that the Supreme Court is considering, in Watson v. Republican National Committee, whether federal law bars states from counting mail ballots that arrive after Election Day, which could change deadlines in 14 states and Washington, D.C.
Forecasts are not results. Polling averages can move in five weeks, and Senate races turn on candidates and local issues as much as on the national mood.
