Greg Lopez, the Republican nominee in the special election in Colorado’s 4th District (to fill Rep. Buck's vacant seat), is well ahead with about two-thirds of the vote counted so far. According to the AP, he leads Democrat Trisha Calvarese, 55-38 percent. That 17-point margin is roughly in line with how the district voted in the last presidential election (for Trump by 19 points).

Perhaps uniquely among states that have held their primaries so far, Colorado voters are particularly concerned with on housing, according to a March poll from New Bridge Strategy/Aspect Strategic/The Colorado Polling Institute. Asked in an open-ended question to name the most important issue for the state government to address, 23 percent of likely voters in the state named homelessness, housing affordability or lack of housing — more than any other issue area. Twenty-one percent named issues related to the economy, including taxes, the cost of living, jobs and inflation. Fourteen percent named issues related to immigration. No other issues were named by more than 6 percent of respondents.

The AP projects that Biggs has defeated Burns in the GOP runoff in South Carolina's 3rd District. With more than 95 percent of the expected vote reporting, she leads 51.1 percent to 48.9 percent — what looks to be a narrow win. This is a somewhat surprising result: Trump had endorsed Burns, who led in the initial primary vote on June 11 and even had an endorsement from the third-place finisher.

But Biggs may have triumphed thanks to more than $500,000 in outside help from two conservative super PACs that have been spending against more anti-establishment candidates in GOP primaries like Burns. Per FEC data, Conservatives for American Excellence and America Leads Action spent mostly against Burns but also made some outlays to support Biggs.

With 24 percent of the expected vote in, Mannion is leading Hood in the Democratic primary in the 22nd Congressional District, 60 percent to 40 percent, according to the AP. Hood had hoped to position herself to Mannion's left on issues like abortion and has a fundraising advantage, as Geoffrey wrote earlier. But Mannion, a state Senator, is a well-known entity in much of the district.

And with that, we’re calling a lid on one of the busiest primary nights of the year! Here’s a recap of what went down.

First, in the two highest-profile races of the night, controversial incumbents went 1-for-2:

- In New York’s 16th District, the AP has projected that Westchester County Executive George Latimer will defeat progressive Rep. Jamaal Bowman in the Democratic primary. This race was defined largely by internal Democratic divisions over the Israel-Hamas conflict and the influence of pro-Israel groups, although controversies about Bowman's past behavior certainly made him more vulnerable.

- In Colorado’s 4th District, the AP has projected that Rep. Lauren Boebert will win the GOP nomination. Boebert caused a lot of grumbling after switching districts from the 3rd, on the other side of the state, but she ultimately won easily thanks to her big fundraising advantage, Trump’s endorsement and ton of name recognition.

It was a bad night for Trump-endorsed candidates in competitive races, three of whom lost:

- The AP has projected that Air National Guard Lt. Col. Sheri Biggs will narrowly defeat Trump-endorsed pastor Mark Burns in the Republican runoff in South Carolina’s 3rd District..

- According to the AP, Jeff Crank, a conservative talk radio host, won the Republican primary in Colorado’s 5th District, defeating state party chair and Trump endorsee Dave Williams.

-In the Republican primary for U.S. Senate in Utah, Rep. John Curtis defeated Trump-endorsed Riverton Mayor Trent Staggs. Curtis will follow in the moderate footsteps of Sen. Mitt Romney, who is retiring from this seat.

Both parties also chose their nominees for some competitive House races this fall — and in general, they chose the more electable options.

- The AP has projected attorney Jeff Hurd will win the Republican primary in Colorado's 3rd District. Republicans avoided nominating former state Rep. Ron Hanks, who was so conservative he risked losing this light-red seat to Democrat Adam Frisch.

- The AP has projected that state Rep. Gabe Evans has won the Republican primary for Colorado's 8th District over state-party-endorsed Janak Joshi. Evans will face off in November against Democratic Rep. Yadira Caraveo, who won this district by just over 1,600 votes in 2022.

- In New York’s 1st District, former CNN anchor John Avlon won the Democratic primary against 2020 nominee Nancy Goroff. He’ll face Republican Rep. Nick LaLota this fall.

- In New York’s 22nd District, the AP has projected that state Sen. John Mannion will win the Democratic primary against DeWitt Town Councilor Sarah Klee Hood. Mannion will face Republican Rep. Brandon Williams in this blue-leaning district in the general.

However, conservative Republicans did score a win in one solid-red open seat:

- In Utah’s 3rd District, the AP has projected that state Sen. Mike Kennedy, who was endorsed by Sen. Mike Lee, will win the GOP nomination to succeed Curtis. Kennedy outpaced four other contenders, including trampoline tycoon Case Lawrence, who self-funded his bid but came in second place.

Finally, a number of other incumbents also beat back notable challengers tonight:

- The AP has projected that incumbent Gov. Spencer Cox will defeat state Rep. Phil Lyman in the Republican primary for Utah governor. However, Lyman, who was running to Cox’s right, still took more than 40 percent of the vote.

- Moderate Rep. Blake Moore also won renomination in Utah’s 1st District, according to the AP, easily dispatching a more conservative challenger.

- The AP has projected that Rep. Claudia Tenney will win the Republican primary in New York's 24th District over businessman Mario Fratto, who came within 14 points of unseating her in 2022.
