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, 10:12 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!

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.

Schaefer holding onto his lead in Missouri's 3rd

With 43 percent of the expected vote in so far, Schaefer's lead is holding at about 49 percent to Onder's 36 percent, according to the AP. Schaefer has establishment Republican backing, but Onder has support from Trump, the House Freedom Fund and the Club for Growth in this very conservative district.

Another vote drop in St. Louis — this one better for Bell

St. Louis city just reported another batch of votes in the Democratic primary for Missouri's 1st, and unlike the last batch, which went overwhelmingly for Bush, Bell actually won this one. The drop didn't change the districtwide numbers much: Bell leads Bush 55 percent to 42 percent with an estimated 33 percent of the vote counted.

Bailey wins the GOP nomination for Missouri attorney general

The AP has projected that incumbent Andrew Bailey will win the Republican primary for Missouri attorney general. With 32 percent of the estimated vote counted, the race is not close: Bailey leads Will Scharf 65 percent to 35 percent. Although Scharf is one of Trump’s personal attorneys, this was hardly a victory for moderates; both candidates in this race were hard-right culture warriors.
