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!

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!
