According to the Associated Press, businessman and state Rep. Gabe Evans has won the Republican Primary for Colorado's 8th Congressional District. With 64 percent of the vote reporting, he currently has a 78 percent to 22 percent lead over his opponent, Janak Joshi, a physician and former state representative.

Evans will face off against incumbent Democratic Rep. Yadira Caraveo, who won the district by 1,600 votes in 2022. It is the most competitive seat in Colorado according to the Cook Political Report's Partisan Voter Index.

The AP projects that Lauren Boebert will win the GOP nomination in Colorado's 4th District. With 66 percent of the expected votes in and Boebert at a sizable lead above her next closest competitor, Deb Flora, it's (as my dad would say) all over but the crying. Boebert had a big fundraising advantage, Trump's endorsement, and obviously has a ton of name recognition, but after the headlines of the last year, that didn't necessarily equate with a guaranteed win. She had her work cut out for her in this new district, according to her campaign, where voters were skeptical of her reputation. But she reportedly put in the work, trekking all across this district over the last few months. A spokesperson for her campaign told me last month that on Easter weekend alone, she drove the district end-to-end for multiple campaign stops, totaling about 1,000 miles. Whatever combination of hard work, notoriety and deep pockets seems to have worked, and now she can all but cruise into the seat in November in this deep red district.

With nearly half of the vote reporting in Colorado's 3rd and 8th Congressional Districts, mainline Republican candidates Jeff Hurd and Gabe Evans have pulled ahead of the competition. Evans is endorsed by both Trump and the conservative activist organization Americans for Prosperity, funded by the influential Republican Koch brothers, so no surprises here really. Hurd's race was closer though. Going into the night he had a clear fundraising advantage and the support of several "normie" Republican organizations — like the national cattleman's association and the association of automobile dealers. A victory for Hurd (which looks likely, but there's quite a few rural votes left to be counted) would be a defeat for the other MAGA-aligned candidates in the race — such as Ron Hanks, who has previously called himself a "pro-Trump warrior".

In perhaps the highest-profile race of the evening, Latimer leads Bowman 56 percent to 44 percent in the Democratic primary for New York's 16th District, with a little more than a quarter of the overall expected vote reporting, per the AP. Bowman is running up huge numbers in the small part of the district that's in the Bronx — he leads 84 percent to 16 percent there — but about nine-tenths of the district's population lives in Westchester County, where Latimer currently leads 69 percent to 31 percent.

According to our analysis of primaries this cycle through May 21, 41 percent of Democrats' nominees for House, Senate and governor are women, compared with just 16 percent of Republicans' nominees. It wasn't until June 11 that Republicans nominated a nonincumbent woman in a seat they're strongly favored to win in November: Julie Fedorchak in North Dakota's at-large district. But today's races present a couple more opportunities for Republican women to make gains.

One race I'll be watching is the runoff between Biggs and Burns in South Carolina's 3rd. Biggs has been endorsed by VIEW PAC, one of the organizations trying to elect more Republican women, but Trump endorsed Burns. This will be a safe Republican race in November, so a Biggs win would likely add a woman to the Republican conference.

In Utah, incumbent Rep. Celeste Maloy faces a serious challenger, even though she has an endorsement from Trump. Her challenger has been endorsed by Sen. Mike Lee, Sen. Rand Paul, Sen. Tommy Tuberville and former presidential candidate Vivek Ramawamy and is painting Maloy as too "D.C."

In Colorado, there are only two Republican women running today, and they are facing off against each other in the 4th Congressional District. Flora has been endorsed by VIEW PAC, but Boebert has the support of Maggie's List, which is another of the GOP groups dedicated to electing more women. This is the second time we've seen two GOP women's groups endorse against each other in primaries thus far. Last week, in South Carolina's 1st, Rep. Nancy Mace was endorsed by VIEW PAC, while Winning for Women supported her challenger, Catherine Templeton. Mace prevailed*.

While Mace and Boebert both had backing from Trump, Boebert is a member of the Freedom Caucus, while Mace is not, which could explain why VIEW PAC backed Mace but not Boebert. In 2022, VIEW PAC endorsed a challenge to Rep. Marjorie Taylor Greene in her primary, another female member of the Freedom Caucus.

In Democratic primaries today, EMILYs List, the prominent political action committee formed to elect pro-choice Democratic women, has endorsed just two nonincumbents, both in New York: Goroff in the 1st and Laura Gillen in the 4th. Gillen, a lawyer and former Hempstead Town Supervisor, is unopposed in the primary, and she stands a decent chance of defeating incumbent Republican Rep. Anthony D'Esposito in November.

I'll keep you updated on these candidates and more throughout the night.
