Undecided races of the 2024 election: Live results and analysis

New York's 4th and 19th Districts are the fourth and fifth House seats that Democrats have flipped from red to blue so far, joining one other seat from New York and two seats that were dramatically redrawn in redistricting. However, Republicans have flipped six seats from blue to red: three in North Carolina that flipped because of redistricting, and then three in the northern presidential swing states. Altogether, Republicans have netted just one seat thus far — which goes a long way toward explaining why they're on pace to win about as many seats as they did in 2022.

On the presidential and Senate side, of course, it's a different story. All the flips there have been toward Republicans. Trump has so far been projected to win five states that Biden carried in 2020, and Republicans have made a net gain of three seats in the Senate — so far, all in states that Trump carried by a healthy margin.

Voters in Nebraska and Missouri are projected to approve ballot measures that would guarantee workers paid sick days and the measure is well ahead in Alaska, according to The New York Times. The Missouri and Alaska measures would also eventually raise the minimum wage in those states to $15 an hour.

With nearly all of the expected vote reported, the Nebraska measure passed 74% to 26%, and Missouri's passed 58% to 42%. With a little more than three-quarters of the expected vote in in Alaska, its measure is ahead 57% to 43%, but hasn't been officially projected yet.

The states will join 14 others and Washington, D.C. in guaranteeing paid sick days for workers for short-term illnesses and to take care of sick family members. Most of the measures require employers to allow employees to accrue time off for hours worked and prevent them from retaliating against employees who use them. The push for paid sick days predates the COVID-19 pandemic, but became even more pressing while the country tried to control the spread of the virus. While a short-lived federal law allowed workers affected by the coronavirus to take paid time off, the U.S. remains one of the only among its few peer countries that does not have a federal law guaranteeing paid sick days or longer term paid medical and family leave for workers.

Harris made paid family leave (which provides for longer-term leaves, not just sick days) a key part of her platform, but it didn't translate into support for her candidacy. But it's not unusual for voters in red states to pass progressive ballot measures while also voting for more progressive candidates who may not support those same measures. These three are just the latest of many worker-friendly policies have passed by ballot initiative across the country in recent years.

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.
