With 29 percent of the expected vote reporting in the Republican primary for Oregon's 4th District, Air Force veteran and attorney Monique DeSpain leads former Keizer city councilmember, Amy Ryan Courser, 56 percent to 43 percent. DeSpain has an endorsement from Maggie's List — one of the GOP groups formed to elect more women to office that we've been tracking endorsements from this primary cycle. The winner of this primary will face incumbent Democrat, Rep. Val Hoyle in what's expected to be a competitive race.

To our conversation on issue-related polling vs. vibes, I read that post today too, Nathaniel, but I think there's still something interesting in the polling around what voters say they're focused on. I've been tracking this throughout the primaries, and I think it can help hone in on how voters in different states are thinking about the issues that impact their communities. For example, we learned that Maryland voters are more focused on crime than voters in other states. Georgia Democrats are particularly worried about healthcare. Illinoisans are focused on crime and taxes.

These kinds of insights perhaps don't tell us who voters are going to choose at the ballot box, but they do tell us something about how voters are thinking about politics. And while a lot of voting choices may be just vibes, which vibes voters care about are probably connected to the issues they see as important in their local communities.

Mere minutes after polls closed in Oregon's 6th District, ABC News reports that Erickson is projected to win the GOP primary. With about 37 percent of the expected vote counted, Erickson leads the field with 75 percent. The businessman only spent $43,000 on his primary bid but easily secured a rematch against Salinas, who is favored to win a second term in this relatively new district.

The night's only halfway over! And for anyone who took my advice to watch today's Pacers-Celtics game, overtime wrapped up just in time for our last polls to close.

As of 11 p.m. Eastern, polls are now closed in the Idaho panhandle and nearly all of Oregon, plus the California 20th District special runoff election to fill Kevin McCarthy's vacant House seat.

It's primary day in Georgia, Idaho, Oregon and Kentucky! We've got a break from Senate contests tonight — none of these states have U.S. Senate seats up for election in 2024 — but we'll be closely tracking U.S. House primary action and some other key races. Here's a quick roadmap of what to expect throughout the evening.

Kentucky has the earliest poll closing time tonight (6 p.m. Eastern in the eastern part of the state, 7 p.m. Eastern in the western part), but also probably the sleepiest races, with no seriously competitive House contests. We'll see more action in Georgia, where polls close at 7 p.m. Eastern and we're tracking a competitive open-seat GOP primary and a challenge to an aging Democratic incumbent. Plus, a competitive state Supreme Court race could tell us something about how much abortion is motivating voters in a key swing state.

After that, you may want to take a dinner break or, perhaps, watch Game 1 of the NBA Eastern Conference finals. The next polls close at 10 p.m. Eastern in (most of) Idaho, where incumbent centrist Republican Rep. Mike Simpson is fending off a conservative challenger. Finally, (most of) Oregon's polls close at 11 p.m. Eastern; a couple of primaries there have seen big spending from controversial sources.

As a bonus nightcap, a special election runoff in California will have an immediate impact on House majority math as voters fill former Speaker Kevin McCarthy's old seat, which has been empty since the start of the year. Polls close there at 11 p.m. Eastern as well.
