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!

It's not over for Onder in Missouri's 3rd

Expounding on what Monica said: Even though Schaefer has a 10-point lead on Onder right now in the Missouri 3rd GOP primary, I'd bet on Onder making up most, if not all, of that ground. That's because Schaefer's lead is built on his strength in the counties clustered around his home base of Columbia, Missouri. However, many counties not near Columbia have yet to report, including Onder's home area of St. Charles County. So the Trump-endorsed candidate may yet still win here.

Slotkin flipped her seat in 2018

As Geoffrey just mentioned, the AP has projected that Elissa Slotkin will win the Democratic nomination for Senate in Michigan. She has backing from EMILYs List, which will help in November, given that that race is expected to be close. Slotkin is one of several Democratic women who flipped her district from red to blue in 2018, which was a record-setting year for Democratic women running and winning. She was also one of many "Obama alum" who ran and won that cycle.

Schmidt has won the GOP primary for LaTurner's open seat

In the GOP primary for Rep. Jake LaTurner's open seat, the AP projects that former state Attorney General Derek Schmidt has secured his spot on the ballot this fall — and most likely a seat in Congress in this safe red district. With 43 percent of expected votes reporting, Schmidt has taken in 50 percent of the vote, while his main opponents, former LaTurner staffer Jeff Kahrs and rancher and feedlot owner Shawn Tiffany are each sitting around 20 percent.

Both Kahrs and Tiffany tried to run to Schmidt's right and were close on his tail in fundraising, but Schmidt — who was also Kansas Republicans' gubernatorial nominee in 2022 — benefited from statewide name recognition, Trump's endorsement and the support of over $300,000 in outside spending, including $186,000 from Americans for Prosperity's super PAC. That was enough to secure him a win tonight.

Kehoe's margin would be a blow to polls

Nathaniel, if that margin holds in the Missouri gubernatorial race, pollsters will have some 'splaining to do. For most of the year, Ashcroft had a comfortable lead, and Kehoe pulled even only at the beginning of July. Since then, the two have been neck and neck in one of the most-polled primary races of the cycle.
