With an estimated 50 percent of the expected vote counted in the Utah Republican primary for governor, the AP projects that Cox, the incumbent, will win. He currently leads Lyman 60 percent to 40 percent. Cox was booed at this year's nominating convention, but the convention in Utah hasn't really had its finger on the pulse in recent cycles.

With 62 percent of the vote estimated to have been counted in the GOP primary for Utah’s 2nd District, per the AP, Maloy has just a 52 percent to 48 percent lead over Jenkins. Maloy’s lead is built on strong performances in Salt Lake and Davis counties, in the Salt Lake City metro area, while Jenkins is doing well in Washington County, home to St. George in the state’s southwest corner. This race could come down to how some of the more rural counties in between vote.

This wasn't a race that we expected to be close, but the AP projects that Democratic Rep. Alexandria Ocasio-Cortez will easily win renomination in New York's solidly blue 14th District. I note the contest only because she faced a primary challenge from former insurance executive Marty Dolan, who originally ran against Bowman in the 16th District primary, but switched races to take on Ocasio-Cortez. Dolan mostly got attention from conservative media outlets — Ocasio-Cortez is their bête noire — but it turns out that, amazingly, appearances on Fox News aren't a good way to win a Democratic primary.

In Colorado, the state party organization is in a state of constant disarray, but they found the time to endorse a number of candidates in competitive GOP primaries tonight. Those candidates aren’t doing particularly well: in the 3rd District, former state Rep. Ron Hanks is losing handily to attorney Jeff Hurd; in the 5th District, state party chairman Dave Williams lost to radio host Jeff Crank, and in the 8th District, former state Rep. Janak Joshi lost in a landslide to state Rep. Gabe Evans.

While that’s a poor track record for the state party itself, it’s music to the ears of national Republicans who want to win House races. Hanks, Williams, and Joshi were poor fundraisers who had lots of baggage in their backgrounds and would have made holding onto even GOP-leaning seats more of a challenge. With all three losing tonight, national Republican groups can focus on the most competitive seat, the 8th District, and feel a lot better about the 3rd and 5th Districts.

After coming within 600 votes of losing her seat in the 2022 midterm election and enduring an awful year in her personal life, Colorado Rep. Lauren Boebert has ditched her district to attempt to win over Republican voters on the other side of the state, in the 4th District. This seat, which was previously held by Republican Rep. Ken Buck — who resigned earlier this year after announcing his retirement last year — is more reliably red, having gone for Trump by a margin of 19 percentage points in 2020 (compared to an 8-point margin in the 3rd). So if Boebert can secure the GOP nomination, she'll all but guarantee herself a spot in the next Congress.

Standing in her way are some primary candidates with more local cachet, such as former state Sen. Jerry Sonnenberg and Deborah Flora, a former Miss Colorado and local talk radio host. However, Boebert has a major fundraising advantage (she's raised $3.7 million, compared to the next-highest raiser, Flora, who's raised less than half a million), as well as Trump's endorsement, and the sole poll we have for this race shows her up 35 percentage points. So she's definitely got a solid shot at the primary in her new district.

In addition to the race to fill this seat in the 119th Congress, there is a separate special election to see out Buck's term. Republicans are favored to win that race.
