Missouri, Michigan, Washington and Kansas primaries 2024: Cori Bush loses
The fields are set for Michigan's Senate and Missouri's governor contests.
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!

Missouri's other contentious House primary
The Republican primary in the dark-red 3rd District has gotten a fraction of the attention of Bush's contest in the 1st, but it has similarly high ideological stakes. Old-guard Republican Rep. Blaine Luetkemeyer is retiring, and it seems likely he will be replaced by a more hardline conservative, former state Sen. Bob Onder (whom Luetkemeyer also defeated in the 2008 primary en route to winning this seat in the first place). A bunch of GOP heavy hitters (Trump, the House Freedom Fund, the Club for Growth) have lined up behind Onder, who was known for his obstructionist ways in the state legislature.
Not everyone is thrilled about the prospect of Onder heading to Congress, however. Establishment-aligned super PACs have spent $4.9 million opposing Onder or supporting his main opponent, former state Sen. Kurt Schaefer, outdistancing the $3.0 million groups have spent to boost Onder or attack Schaefer. Luetkemeyer is supporting Schaefer as well, but it doesn't seem like he's catching on. Onder's campaign recently released a poll from Remington Research Group showing him leading Schaefer 34 percent to 14 percent, with five minor candidates combining for 16 percent, and 35 percent undecided. Even if we assume that poll is exaggerating Onder's support, it's unlikely that it's off by 20 whole percentage points.

A Squad member could lose tonight in Missouri's 1st
Perhaps no district in the country has seen more political activism in the past decade than Missouri's 1st District. In 2020, on her second try, now-Rep. Cori Bush — a progressive activist who first rose to prominence in the 2014 Ferguson protests in this district — defeated an entrenched incumbent representative in the Democratic primary in this safely blue seat, and she instantly made a name for herself as an activist legislator in Congress.
But her contrarianism — for example, she was one of just six Democrats to vote against President Joe Biden's infrastructure bill — has rubbed many the wrong way. It doesn't help, too, that the Department of Justice is investigating her for paying her husband for personal security services out of her campaign's bank account. As a result, Bush is now facing a serious primary challenge of her own from St. Louis County Prosecutor Wesley Bell.
Like Bush, Bell was first elected as a progressive in the wake of the Ferguson protests, but in this race he has inevitably become associated with the centrist and conservative donors and groups backing his campaign — most notably the American Israel Public Affairs Committee. AIPAC's super PAC has spent a whopping $8.4 million either supporting Bell or opposing Bush, who has been one of Israel's loudest critics in Congress over its conduct in the war against Hamas.
All told, pro-Bell groups have outspent pro-Bush groups $12.1 million to $2.9 million, according to OpenSecrets, and Bell's actual campaign has outraised Bush's $4.8 million to $2.9 million as well. But with all the advantages of incumbency as well as plenty of local endorsements, Bush will not be easy to defeat. A July 21-24 poll conducted by the Mellman Group/Democratic Majority for Israel gave Bell 48 percent support and Bush 42 percent, but since DMFI supports Bell and internal polls usually overestimate their preferred candidate's support, that implies the two candidates are neck-and-neck.

Welcome!
The presidential news cycle certainly hasn't let up over the past few weeks, and you'd be forgiven if you haven't been paying much attention to downballot primary contests. But Kamala Harris's VP pick wasn't the only big political news today — it's also the busiest election day left before the big day in November.
Voters in four states hit the ballot boxes today to weigh in on which Democrats and Republicans will be on their ballots this fall, and we're tracking over a dozen key congressional, gubernatorial and other races in Missouri, Michigan, Washington and Kansas. Polls close at 8 p.m. Eastern in Missouri and most of Michigan and Kansas, so we'll expect a steady flow of results after that, until the next and last polls close in Washington state, at 11 p.m. Eastern.
It's our last primary live blog of the season, so we hope you'll join us!
