While the overall result has differed, the Vermont map below showcases a similar trend to Massachusetts. As Nathaniel pointed out, Boston and its well-to-do suburbs leaned towards Haley. In Vermont, Haley's strongest results came in areas just across the New Hampshire border from Dartmouth College and in the stretch of land between Montpelier and Burlington, which benefit economically from those population centers and a few prominent ski resorts.

In 2022, our analysis showed that just 48 percent of Republican women in open primaries endorsed by VIEWPAC (a PAC dedicated to electing more women) won. As we observed at the time, VIEWPAC was willing to endorse candidates running against Trump endorsees, which was a bold, but losing, strategy in 2022. Tonight, VIEWPAC candidates in open primaries are not having a lot of success. As I already mentioned, in Alabama's 2nd District, Caroleene Dobson trails Dick Brewbaker. And in Texas's 26th District, another endorsee, Luisa del Rosa, a small business owner, is in a distant fourth place behind a Trump endorsee, Brandon Gill, with 88 percent of the expected votes in. (Gill has also been endorsed by Club for Growth.) But in Texas's 34th, the race has been called for their endorsee, Maya Flores ... who is also endorsed by Trump.

Nikki Haley's delegate count from Vermont hinges on whether she clears the 50 percent threshold. And right now, she's incredibly close to it. With 68,420 votes cast, Haley has 34,215, which is 4 more votes than the 50 percent plus 1 she needs to sweep the state's delegates. When I simulate 100,000 primaries with that number of total votes and an even 50-50 split, I get a result that's within that tight margin only 3 percent of the time.

Polls have closed in California, and ABC News projects that Trump will win the Golden State. He should easily clear 50 percent and claim all of the state's 169 delegates.

Earlier I wrote that although more Republican women are running, the GOP conference is still largely represented by men. North Carolina, where polls just closed, nicely illustrates some of the reasons that Republican women continue to trail Democratic women by such large margins, in Congress. North Carolina has low female representation in their state legislature (which is just 29 percent female), and that limits their recruitment from that pool. And in today's open primaries in safely Republican districts where the GOP primary will effectively decide the next representative, women aren't among the most competitive. As Kaleigh wrote earlier, in the 8th District outside Charlotte, the two GOP front runners are state Rep. John Bradford, and Baptist minister Mark Harris. And in the 10th District, the race is largely between state Rep. Grey Mills and Pat Harrigan, a gun manufacturer. There are several non-incumbent women running in the state today, but none of the groups we are watching that support Republican women (Winning for Women, VIEW-PAC, E-PAC or Maggie's List) have made endorsements.
