We tracked the undecided races of the 2024 election

ABC News reports that Republican Jeff Hurd is projected to win the congressional seat in Colorado formerly occupied by Rep. Lauren Boebert (who ran in a neighboring district). The move was a risky bet for Republicans, as Boebert just barely eked out a win in 2022 before leaving to run for another seat. The move ultimately worked in her party's favor, however: With 94% of the expected vote in, Hurd leads his challenger, Democrat Adam Frisch, 50% to 46%.

As of Monday, Hurd was ahead by about 13,500 votes — a much larger margin than the approximately 600 votes Boebert won by in 2022. But, notably, Hurd overcame a massive fundraising deficit against Frisch, who had one of the largest congressional war chests in the nation. Frisch has already conceded.

Over the weekend, ABC News reported that Democrat Marie Gluesenkamp Perez is projected to win reelection in Washington's 3rd District. This is a Trump-friendly seat in southwest Washington that played host to one of 2022's closest races, when Gluesenkamp Perez won by fewer than 3,000 votes over Republican Joe Kent. But despite Kent returning for another bout — and with a more professional campaign — the mechanic and moderate Democrat won a more comfortable victory this time around; she currently leads Kent by 4.2%, or about 16,000 votes, with 93% of the expected vote reporting. And that's with Trump carrying the district by what will likely be a sizable margin.

ABC News reports that Trump is projected to win Arizona. That was the last unresolved state on the presidential level, so we now know that Trump will win the Electoral College 312-226 — a sweep of the seven big swing states.

ABC News reports that Democratic Sen. Jacky Rosen is projected to win reelection in Nevada. Her lead over Republican Sam Brown is up to 48% to 46%. Still, that's narrower than the polls suggested going into Election Day. Rosen becomes the third Democratic Senate candidate to win while Trump was carrying their state — all by the skin of their teeth.
