Missouri, Michigan, Washington and Kansas primaries 2024: Cori Bush loses

The fields are set for Michigan's Senate and Missouri's governor contests.

Last Updated: August 6, 2024, 6:01 PM EDT

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!

Marlinga looking good

We're finally up to 10 percent of the expected vote reporting in Michigan's 10th District, and 2022 nominee Carl Marlinga looks likely to be the Democratic nominee for the second time in a row against GOP Rep. John James. He leads the field with 46 percent. Marlinga did not receive outside support from major Democratic groups in 2022, but lost by only 1,600 votes. The burden will be on him to convince those same players to invest in him against James this time around.

St. Louis County gets in on the action

St. Louis County just reported its first tranche of election day votes too, and Bell won it by a margin similar to his districtwide lead. The AP now estimates that 40 percent of the vote is now counted in Missouri’s 1st District, and Bell still leads Bush 55 percent to 42 percent.

Social media is not real life

In Missouri’s secretary of state GOP primary, the most talked-about candidate was probably Valentina Gomez, a 25-year-old real estate investor whose provocative, homophobic campaign videos ("don’t be weak and gay," she declares in one, while she burns a pile of books with a flamethrower in another) drew national attention. But in the latest piece of evidence that Twitter isn't real life, she's currently in a distant 6th place with just 7.5 percent.

Checking in on Trump's endorsees

We're monitoring the 25 candidates Trump has endorsed across 22 races. So far, pretty much every endorsee has won or is leading in their primaries, although many faced no opposition. However, Trump is guaranteed to have at least a couple of losers in Missouri's governor's race after he endorsed all three of the high-profile Republicans running. Additionally, one notable contender he endorsed in a competitive House primary — Onder in Missouri's 3rd District — is currently trailing.
