Undecided races of the 2024 election: Live results and analysis

In Iowa’s 1st Congressional District, in a rerun of the 2022 race in the seat, incumbent Republican Rep. Mariannette Miller-Meeks currently leads Democratic former state Rep. Christina Bohannan by just 799 out of 413,502 votes cast, with all precincts reporting. That's a margin of just 0.2 percentage points, according to the Iowa Secretary of State. In Iowa, candidates involved in any race within 1 percentage point can request a recount that will be funded by the state.

We don’t know yet exactly how many provisional ballots or additional absentee ballots there are to be considered for this seat, but it’s fairly unlikely that there would be enough to move either candidate out of recount range (they’d need more than a 4,000 vote margin among any remaining ballots for that to happen).

This will be the second time in the last three cycles that Iowa’s 1st District ends up in recount territory. In the 2020 election for the seat, Miller-Meeks’s first race for Congress came down to just six votes. In 2022, Bohannan felt short by almost 7 percentage points.

Looking at Pennsylvania's Senate race, Republican Dave McCormick leads Democratic Sen. Bob Casey Jr. by about 0.5 points, 48.95% to 48.44%, with 97% of the expected vote reporting. ABC News estimates that perhaps as many as 300,000 votes are left to be counted, however, and nearly 130,000 of those are in deep-blue Philadelphia. Some back-of-the-envelope math: If we assign the outstanding votes based on the current margins in those counties, Casey would end up leading by around 16,000 votes once all votes are reported. Now, we don't know just how those outstanding votes will actually break, and whether the real total left will be around 300,000 or a bit less or more — all critical aspects to this. But this does suggest that Casey might just be able to survive even as Harris lost to Trump in the presidential race.

ABC News projects that Democrats have won Indiana's 1st District and Washington's 8th District, while Republicans have won Arizona's 2nd, California's 3rd and California's 40th.

None of these projections are terribly surprising. Democratic Reps. Frank Mrvan and Kim Schrier were considered likely to win in Indiana and Washington, per our preelection forecast. Same with Republican Rep. Young Kim in California's 40th District and Republican Rep. Kevin Kiley in California's 3rd. And while a well-regarded pre-election poll had found Republican Rep. Eli Crane tied with Democrat Jonathan Nez in Arizona's 2nd, in the end, Crane ended up pulling it out.

ABC News has projected that Republican Ryan Mackenzie will defeat Democratic Rep. Susan Wild in Pennsylvania's 7th District. The seat, which sits in the eastern part of the state, but to the north of the Philadelphia region, has been closely contested during Wild's three terms in office. 538's forecast gave Wild an edge coming into Election Day, giving her about a 7-in-10 shot of winning reelection. But Mackenzie leads by 1.4 points, 50.7% to 49.3% with 99% of the expected vote reporting.
