Undecided races of the 2024 election: Live results and analysis

The fight for the House got a little bit clearer overnight with another three race projections in contests with vulnerable GOP incumbents. ABC News reports that Rep. Ryan Zinke is projected to win reelection in Montana's 1st District, but Rep. Anthony D'Esposito is projected to lose reelection in New York's 4th District and Rep. Marc Molinaro is also projected to lose reelection in New York's 19th District.

All three Republicans were locked in rematches from 2022, and while Zinke looks like he'll improve upon his margin — he leads Democrat Monica Tranel by 7 points — D'Esposito and Molinaro lost ground. D'Esposito trails Democrat Laura Gillen on Long Island by about 2 points, as does Molinaro in upstate New York, who trails Democrat Josh Riley. Both races currently stand at 51% to 49%. And while we won't have granular data for a little while, it's possible that Trump carried both of those districts.

In one of the only House upsets to come out of Tuesday, ABC News reports that Nebraska Republican Don Bacon is projected to win reelection against Democrat Tony Vargas in the 2nd District. He leads by 2 points, 51% to 49%. There was general consensus that Bacon was highly vulnerable this cycle, especially because Harris looked likely to romp to victory (and is projected to win) in Nebraska's 2nd District, which casts its own electoral vote. 538's forecast put Vargas as a two-to-one favorite to win (classified as a "lean Democrat"), and at Inside Elections we rated the race Tilt Democratic (also one tick off of "Toss-up"). But Harris is projected to win the Omaha-based seat by only 3.7%, and Vargas fell short yet again.

Democratic candidates in the House and Senate races performed slightly better than Harris, and ABC News is also reporting that Rep. Susie Lee is projected to barely hold onto her House seat in the state's 3rd Congressional District. With 98% of the expected vote reporting, she has 51% to her Republican challenger's 49%.

The state has four seats in the House, and Democrats hold the three seats in and around Las Vegas, where the vast majority of voters live. Republicans had aimed to flip all three seats, but Democrats held them at bay. Lee's was the closest of these contests, rated as a toss-up in our forecast.

After days of counting in the extremely close presidential race in Nevada, ABC News reports that Trump is projected to win the state's 6 electoral votes. With 97% percent of the expected vote reporting, Harris has 47% to Trump's 51%. Nevada has voted for the winner in every presidential contest since 1912 except 2016, when the state went for Hillary Clinton, who did win the popular vote. It's been trending to the right of the country as a whole in recent years, and Biden won the state by only 2 points in 2020 compared to 4 points nationally.
