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.

In the downballot races for the Kentucky legislature, Republicans aligned with the "liberty" wing of the party are taking on more establishment Republicans. Some of these conservatives are recent incumbents who won seats last cycle, while others are newcomers this year, but in general they take a harder line against government spending than what they call "establishment" Republicans.

Many in the liberty wing are endorsed by national PACs like Americans for Prosperity, and PACs backing "school choice" measures that would allow tax dollars to go to private schools. Battling over support for public schools has divided the party in other states, like Texas, and I've written about the universal school voucher movement's gains over the past two years.

Some swing state Republican Parties have also torn themselves apart over even the tiniest ideological differences in swing states around the country. Battles like those in Kentucky will help shape the general election to come, and could determine the direction the party takes in governing should it win big in November.
