Which U.S. House races are still uncalled? Can Democrats Still Win a Majority?

It’s been a week since Americans cast their ballots on Election Day, and control of the U.S. House of Representatives remains undetermined.

Republicans, who control both the White House and the Senate, will likely remain in power in the House, giving President-elect Donald Trump the opportunity to enact many of the policies he has spearheaded.

As of Tuesday afternoon, 16 races remain unresolved. Democrats would need to win 13 of them to gain the 218 seats needed to take control of the House, which would divide the government and control Trump’s agenda. Democrats lead in just eight of the outstanding races.

Most of the uncalled House races are being held in California, where efforts to make voting easier have increased the time it takes to count all the votes. California also has more than 22 million registered voters, and the huge majority vote by mail, where ballots mailed on Election Day can still be counted up to seven days later.

The most watched race is Alaska, where Republican Nick Begich III leads incumbent Republican Mary Peltola in the race for the state’s only House seat. Begich’s grandfather, former MP Nick Begich, once held this position, but his plane disappeared while traveling to Juneau during the 1972 re-election campaign.

Alaska uses ranked-choice voting, so if no candidate receives 50% of the vote, the race will be decided on November 20.

Another close fight is taking place in Maine’s 2nd District, where Republican incumbent Jared Golden is narrowly ahead of Republican challenger Austin Theriault. The winner of the race will also be decided by automatic ranking recalculation, which will start on Tuesday afternoon.

All Pennsylvania House races have been called. Republicans won 10 of the Commonwealth’s 17 congressional seats and flipped two seats – the Lehigh Valley’s 7th District, where Ryan Mackenzie upset Republican Susan Wild, and the 8th District in northeastern Pennsylvania, where Robert Bresnahan defeated Republican Matt Cartwright.

Republicans will also have to deal with at least two vacancies. The first will be in New York following Trump’s decision to nominate Republican Elise Stefanik (R, New York) as the county’s next ambassador to the United Nations. It is unclear when Stefanik will resign from office – a special election cannot be called until he officially steps down. When this occurs, the special election will be held 70 to 80 days later.

The second vacancy will be in Florida and will replace the position vacated by Rep. Mike Waltz, whom Trump has named as national security adviser. Florida Gov. Ron DiSantis will have to call a special election to fill the position, a process that will likely take several months.
