Undecided races of the 2024 election: Live results and analysis

ABC News projects that Democratic Sen. Tammy Baldwin has won reelection in Wisconsin. With 99% of the expected vote counted, she has 49.4% and Republican Eric Hovde has 48.5%. That's an important win for Democrats, as this was one of Republicans' best remaining pickup opportunities.

Baldwin prevailed despite Trump carrying Wisconsin on the presidential level, making her just the second Senate candidate in the last 10 years to win a state at the same time that the opposite party's presidential candidate was carrying it. However, Trump only won Wisconsin 50% to 49%, so there were actually very few split-ticket voters in this race.

ABC News is projecting that former San José mayor Sam Liccardo will win the Democrat vs. Democrat matchup in California's 16th District, defeating Evan Low, despite Gov. Newsom's endorsement of Low.

Liccardo will replace Rep. Anna Eshoo, also a Democrat, who announced her retirement.

In North Carolina, it looks as though Democrats are on track to hold the state's 1st District as Democratic Rep. Don Davis maintains a narrow lead over Republican challenger Laurie Buckhout. With 91% of the expected vote in, Davis leads by 1 percentage point, 49% to 48%.

While ABC News has not yet projected a winner in the race, Buckhout conceded on Wednesday afternoon. "Don Davis ran a spirited campaign, and I congratulated him on his hard-fought victory earlier today," she wrote in a recent social media post. "While Don and I have different visions, it is obvious to everyone he cares about this district." Given this, it's unlikely she'll request a recount — as she was once considering doing.

Democrats have held the seat since the 1890s, and a Black Democrat has represented the district since 1992. But the race attracted plenty of outside attention as it was one of the only close races in the area. 538's forecast listed it as "likely Democrat."

It's just past 1:00 p.m. Eastern, and so far 10 House seats are projected to flip party control — six toward Republicans and four for the Democrats. One upset is Pennsylvania's 8th District, which unseated Democratic incumbent Matt Cartwright. The district was forecasted as "lean Democrat" in 538's model.

In a few other districts, newly drawn congressional districts were likely responsible for the changes. New congressional maps for the 2024 election meant Republicans secured 10 reliably red seats out of the 14 in North Carolina, where three seats flipped from Democrat- to Republican-held — all of these were marked as "safe Republican" in our forecast. Meanwhile in Alabama, the newly drawn majority-minority 2nd District is projected to elect the state's second Democrat to the House, Shomari Figures, according to ABC News.
