We've talked a lot about the many millions AIPAC spent to take down Bowman in New York's 16th District and about losing GOP candidates who faced sizable outside opposition from groups that opposed more anti-establishment Republicans in primaries. In many of these cases, these outside groups came in and spent a lot of money to oppose or support a candidate, and, unsurprisingly, that influenced the outcome!

But the candidates also mattered a great deal in making outside groups' lines of attack and support count in these primaries. Bowman wasn't that strong to begin with, for instance, and he'd made headlines for many wrong reasons in recent months. Someone like Williams in Colorado had angered a lot of people in his party, making it easier for the sizable outside investment against him to work. In South Carolina, Burns had Trump's endorsement, but he also had a very controversial background that may have encouraged outside groups to invest in Biggs to beat him.

Trump's out-of-pocket endorsements of non-incumbent, contested candidates who really didn’t seem favored to win were a gamble that didn’t pay off. What it did demonstrate is that a Trump endorsement, though it does carry weight in a Republican primary, is not the Midas touch he likes to pretend it is.

Only one race we’re watching is still unresolved (the Republican primary for Utah’s 2nd District), so it’s time for some final thoughts. What big-picture takeaways do folks have from tonight’s results?

—Nathaniel Rakich, 538

The AP projects that state Sen. Mike Kennedy will win the GOP nomination in Utah’s 3rd District, which is currently held by Curtis. Kennedy leads the field with 36 percent, with 72 percent of the expected vote counted. Trampoline tycoon Case Lawrence is set to finish in second with 23 percent. Kennedy, a physician who ran an underdog primary campaign for Senate against Mitt Romney in 2018, will be a shoo-in in the fall.

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.
