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.

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.

As usual, tonight we'll be tracking candidates in Colorado's, New York's and Utah's primaries, along with one runoff in South Carolina, whose campaign websites use the phrase "pro-life," "sanctity of life," "right to life," "protect life," "no abortion," "against abortion" or "unborn" and do not say abortion is an issue of states' rights.

In South Carolina, abortion is banned after six weeks. In the 3rd District runoff there, Biggs describes herself as anti-abortion and has promised to "defend the sanctity of life" if elected. She has also been endorsed by Susan B. Anthony Pro-Life America.

Abortion is banned in Utah after 18 weeks. All four Republican Senate candidates and at least one Republican House candidate in each of the state's four congressional districts are on our list, including 4th District Rep. Burgess Owens, who is running unopposed. Republican Gov. Spencer Cox is also anti-abortion, but he is nevertheless facing a challenge from the right by state Rep. Phil Lyman, who argues the governor is too moderate overall. Whoever wins the primary is likely to succeed in November against the Democratic challenger, state Rep. Brian King.

By contrast, New York law protects abortion rights, and voters may have a chance to enshrine abortion rights into the state constitution if a proposed Equal Rights Amendment makes it onto the November ballot. Three Republican candidates in New York state are on our list. In the Republican-leaning 23rd and 24th districts, Rep. Nicholas Langworthy is running unopposed, and Mario Fratto, who lost to Rep. Claudia Tenney in 2022, is challenging the incumbent from the right again. But the Republican incumbent in the 22nd district, Rep. Brandon Williams, is more vulnerable, as redistricting left the district slightly bluer. Indeed, while New York Democrats plan to campaign on abortion rights to drive voters to the polls in November, Republicans in the state have been downplaying the issue.
