Three months out from the big November election, around a third of all states had yet to hold (non-presidential) primaries. On Tuesday, Democrats and Republicans in Missouri, Michigan, Washington and Kansas went to the polls to pick which candidates will appear on their ballots in the fall.

The electoral fate of a couple endangered House incumbents hung in the balance on this packed primary day. In Missouri, a progressive "Squad" member was defeated by centrist forces, and in Washington, one of only two remaining House Republicans who voted to impeach President Donald Trump was challenged by not one but two Trump-endorsed opponents from his right.

Meanwhile, both parties locked in their nominees for Michigan’s critical Senate race, and the outcomes of Republican primary contests are likely to determine Missouri’s next governor and attorney general. In battleground House districts, the fields were set for competitive fall contests, while in safe red and blue districts, ideological lines were drawn as candidates duke it out in primaries tantamount to election.

As usual, 538 reporters and contributors broke down the election results as they came in with live updates, analysis and commentary. Check out our full live blog below!

While we're waiting ... how bout them Chiefs?

While results in Missouri slowly trickle in, here's some fun Missouri polling. In a mid-June Emerson/The Hill survey, 63 percent of Missourians said that the Kansas City Chiefs remaining in Missouri (as opposed to moving to Kansas) was "very" or "somewhat" important to them, 46 percent of whom said it was "very" important. The Kansas City Royals don't get quite the same enthusiasm: 58 percent of Missourians think the Royals staying in the state is "very" or "somewhat important", of which 38 percent say it's "very" important to them.

Kansas has been trying to lure both teams over state lines in the coming years, with the Kansas legislature passing a plan to make it happen. What Missourians will be able to do about it, we'll just have to wait and see.

Checking in on Michigan anti-abortion candidates

A quick-check in on anti-abortion Republican primary candidates in Michigan: Many of these candidates are incumbents, and it's too early for most competitive races to be called, but the fact that Rogers is projected to win the nomination for Stabenow's Senate seat means that the anti-abortion physician, O'Donnell, has lost.

Lucas Kunce to face Josh Hawley in Missouri

As expected, the AP projects Kunce to win the Democratic primary for U.S. Senate in Missouri, where he currently leads state Senator Karla May by over 40 points. Kunce, a Marine Corps veteran, sought the Senate seat in Missouri in 2022, but lost in the primary.

However, Kunce faces an uphill battle against Hawley in November: The seat is rated as solidly red by the Cook Political Report. Hawley won his first race in 2018 by 5.8 points against popular incumbent Claire McCaskill, and he's likely to win by much more this time around.
