When will the House of Representatives convene?

With hotly contested U.S. House races taking place across the country, it could take days to determine a winner.

In the 2022 midterm elections, it took more than a week for the House of Representatives to be decided. The election took place on November 8, 2022 and AP called the race for the Republicans' 218th seat, securing their majority, on November 17.

Less than one percentage point decides House elections across the country

The razor-thin margins in U.S. House elections across the country mean majority control will be too close for some time.

In Arizona, the gap between incumbent and challenger is less than a percentage point in the state's 6th District, where incumbent Republican Juan Ciscomani is ahead at 49.1 over Democrat Kirsten Engel at 48.6, with 67% of votes counted.

Maine's 2nd Congressional District also has a razor-thin lead as Republican challenger Austin Theriault closed the gap between him and incumbent Democratic Congressman Jared Golden. Golden now has a lead of just 0.7 percentage points over Theriault, with 93% of the vote.

Incumbent Democratic Ohio 9th District Congresswoman Marcy Kaptur, who has been in Congress since 1983, has just a 0.3% lead over her Republican challenger Derek Merrin with 95% of votes counted.

California House will definitely have to watch

With control of the U.S. House of Representatives still at stake, Democrats are focused on winning a handful of key seats in California.

They hope to defeat five incumbent Republicans in the state whose seats are needed for the House change. But so far, Republican members of Congress appear to be holding their districts by a slim majority.

• California's 13th – Incumbent Republican Congressman John Duarte has a shrinking two-point lead over his Democratic challenger Adam Gray, with just over half the vote, 52%, returned.
• California's 22nd – Things are different in the 22nd District, where Republican Congressman David Valadao is ahead by 10 points over Democratic challenger Rudy Salas with 56% of ballots counted.
• California's 27th – Republican Congressman Mike Garcia has a narrow two-point lead at 69% over his Democratic challenger George Whitesides.
• California's 41st: In another close race, incumbent Republican Congressman Ken Calvert has a two-point lead over Democrat Will Rollins at 76%.
• California's 45th – Democrat Derek Tran has closed the gap between himself and incumbent Republican Congresswoman Michelle Steel, but maintains a commanding four-point lead with 70% of votes counted.
