Former President Donald Trump has clinched a second term in the White House, and his Republican Party has won control of the Senate. But control of the House of Representatives is still up for grabs, as is the size of the incoming Senate majority.
In the fight for the House, Democrats are facing an uphill climb to net the four seats needed to flip the chamber, while Republicans only need to win a handful more competitive races to hold onto the majority. With more than a dozen House races still uncalled and many looking close, Democrats would need to hang onto all of their competitive seats and flip a few Republican-held seats to get to the 218 seats needed for the majority.
With votes still being counted, here’s a look at the key races that remain uncalled by the NBC News Decision Desk (read more about how those races are called). While some of the battleground states may be projected relatively quickly, it could take days or even weeks to resolve control of the House.
Presidential battlegrounds
With Trump’s victory in Michigan projected by NBC News Wednesday afternoon, a win in Nevada called early Thursday morning and a victory for Trump declared in Arizona on Saturday evening, every presidential battleground state has now been called.
Senate races left to call
Arizona Senate: Democratic Rep. Ruben Gallego is leading Republican Kari Lake in the vote count, but the race is still too early to call. Lake is trailing Trump’s margin in the state, while Gallego is outperforming Vice President Kamala Harris. Gallego, a Marine veteran, touted his military service in his race against Lake, a former local TV news anchor. Lake ran unsuccessfully for governor in 2022, and she made false claims that her 2022 race was affected by voter fraud.
Pennsylvania Senate: Although Trump is projected to win Pennsylvania, the Senate race there is still too close to call. Democratic Sen. Bob Casey is running for a third term against Republican Dave McCormick, a former hedge fund CEO who ran unsuccessfully for the GOP Senate nomination in 2022.
House control on the line
Control of the House is still unclear with significant competitive races remaining uncalled, including a number of key races in California alone. There are also other races that are not expected to be competitive but have not yet been projected because few votes have been counted.
Alaska At-Large District: Republicans are looking to pick up this seat, which encompasses the entire state, which Trump carried easily. Republican Nick Begich is leading Democratic Rep. Mary Peltola, but he is hovering around the 50% threshold required to win the race outright. If he falls short of that threshold, the race will head to ranked-choice voting, but Republicans are confident they would still carry the seat in that scenario.
Arizona’s 1st District: GOP Rep. David Schweikert is in a competitive race in the Phoenix suburbs against Democrat Amish Shah, a former state legislator.
Arizona 6th District: GOP Rep. Juan Ciscomani is trailing his Democratic opponent, former state Sen. Kirsten Engel, in this competitive district in the Tucson suburbs.
California’s 9th District: Democratic Rep. Josh Harder is narrowly leading his Republican opponent, Stockton Mayor Kevin Lincoln.
California’s 13th District: GOP Rep. John Duarte is locked in a tight race against Democrat Adam Gray, a former state legislator, in this Central Valley district.
California’s 21st District: Democratic Rep. Jim Costa is locked in a close race with Republican Michael Maher, a former FBI agent, in this Fresno-area district.
California’s 22nd District: GOP Rep. David Valadao, one of two remaining House Republicans who voted to impeach Trump after the Jan. 6, 2021, Capitol riot, is leading his Democratic opponent, former state Assemblyman Rudy Salas.
California’s 27th District: GOP Rep. Mike Garcia is in a tight race against Democrat George Whitesides, a former NASA chief of staff and Virgin Galactic CEO, in this Southern California district.
California’s 41st District: Democrats have targeted this Riverside County-based district, and GOP Rep. Ken Calvert is in a competitive race with Democrat Will Rollins, a former prosecutor.
California’s 45th District: GOP Rep. Michelle Steel is leading Democratic Army veteran Derek Tran in one of the most expensive races in the country.
California’s 47th District: Republicans are looking to flip this open seat in Southern California, and Republican Scott Baugh, a former state legislator, is in a competitive race against former state Sen. Dave Min.
California’s 49th District: Also in Southern California, Democratic Rep. Mike Levin is in a tight race against auto dealer Matt Gunderson, a self-described “pro-choice” Republican.
Iowa’s 1st District: Just a few hundred votes separate Republican Mariannette Miller-Meeks and Democrat Christina Bohannan, a former state representative. It is familiar territory for Miller-Meeks, who won her 2020 race by just six votes.
Maine’s 2nd District: Democratic Rep. Jared Golden has been a top GOP target, and he is hovering just above the 50% threshold that would allow him to win outright over Republican state Rep. Austin Theriault, a former NASCAR driver (the state holds ranked-choice elections).
Ohio’s 9th District: Democratic Rep. Marcy Kaptur is locked in an extremely tight race with GOP state Rep. Derek Merrin.
Oregon’s 5th District: Democrat Janelle Bynum narrowly leads Republican Rep. Lori Chavez-DeRemer.
Washington’s 4th District: Republican Rep. Dan Newhouse narrowly leads Republican former NASCAR driver Jerrod Sessler. (Washington’s primary advances the top two vote-getters to the general election, regardless of party.)
Sessler has Trump’s endorsement over Newhouse, who is one of the two Republicans left in the House who voted to impeach Trump after the Jan. 6, 2021, Capitol riot.
