Undecided races of the 2024 election: Live results and analysis

Today, Maine election officials started running ranked-choice tabulations in the still-unresolved race for Maine's 2nd Congressional District. However, it could take days before they are finished and able to declare a winner. If you want, you can watch the process live here:

We already know that Democratic Rep. Jared Golden received 196,189 first-place votes, Republican state Rep. Austin Theriault received 194,030 first-place votes, write-in candidate Diane Merenda received 420 first-place votes, and 12,635 ballots left the first choice blank. But because Maine uses ranked-choice voting, votes for Merenda and blank votes will be redistributed to the candidate those ballots ranked second (or third, if someone used their first two slots for Merenda and a blank). Because of the gap separating Golden and Theriault, there would need to be thousands of "hidden" Theriault voters among those blank ballots in order for him to win, which is quite unlikely.

Late Monday evening, ABC News reported that Republican Rep. David Schweikert is projected to win reelection in Arizona's 1st Congressional District. The wealthy area outside of Phoenix is a GOP stronghold that had been trending more Democratic during the Trump era, giving Democrats hope they could flip the seat. But Schweikert, a seven-term incumbent who's been convicted of numerous campaign finance ethics violations during his tenure, is projected to hold on with 52% of the vote to Democratic physician Amish Shah's 48%, with nearly all of the expected vote reporting.

California has offered a rare ray of sunshine for Democrats in this election, as ABC News reports that Democrat George Whitesides is projected to defeat Republican Rep. Mike Garcia in the state's 27th District, handing Democrats a GOP-held House seat in the northern Los Angeles suburbs. With 88% of the expected vote reporting, Whitesides leads Garcia 51.2% to 48.8%.

Garcia is the fourth House Republican incumbent projected to lose in the 2024 election, but the first outside of New York, which is home to the other three who've gone down. To be clear, Garcia was always in a tough spot: He's routinely had to defend a district that leaned slightly toward Democrats at the presidential level, but he managed to win three times — first in a 2019 special election to pick up the seat from the Democrats, then reelection in 2020 and again in 2022 to retain it for the GOP. But Democrats finally were able to flip his seat back.

ABC News reports that Democratic Rep. Ruben Gallego is projected to win Arizona's U.S. Senate race. After a large batch of votes from Maricopa County was reported tonight, Gallego leads Republican Kari Lake 50% to 48%.

This is a crucial hold for Democrats and guarantees them at least 47 seats in the next Senate (the only unresolved Senate race is now Pennsylvania, which is likely but not certain to go to Republicans). Gallego is also the fourth Senate Democrat this year to win in a state carried by Trump; my colleague Geoffrey Skelley examined this seeming spike in split-ticket voting in an article on Monday.
