Looking ahead to Oregon's results, the Portland-based 3rd District hosts one of the big contests of the night. Longtime Rep. Earl Blumenauer's retirement has left open this solidly blue seat, and three contenders with progressive brands are competing for the Democratic nomination: state Rep. Maxine Dexter, former Multnomah County Commissioner Susheela Jayapal and Gresham City Councilor Eddy Morales. At first blush, Jayapal looked to be the front-runner, as she previously represented close to 30 percent of the 3rd District's overall population — far more than Dexter or Morales. She also sports ties to national progressives via her younger sister, Washington Rep. Pramila Jayapal, who chairs the Congressional Progressive Caucus.

Yet a late campaign cash bonanza may have turned the race on its head, to Dexter's benefit. Pre-primary financial reports through May 1 showed that Dexter had received a massive late boost to bring her campaign total to $919,000, ahead of Jayapal's $773,000 and Morales's $606,000. And from May 2 to May 19, Dexter reported $419,000 in major contributions, far more than her opponents' combined $150,000. Meanwhile, outside groups have spent more than $5 million either supporting Dexter or opposing Jayapal. The 314 Action Fund, a progressive group that supports candidates with science backgrounds, has doled out $2.2 million on ads promoting Dexter and a super PAC with unclear ties, Voters for Responsive Government, has spent $3.2 million on spots attacking Jayapal.

This surge of money has brooked controversy because it appears at least partly connected to the American Israel Public Affairs Committee, a bipartisan pro-Israel group opposed to progressive critics of Israel's military action in Gaza. While Dexter supports "a negotiated cease-fire" and Morales has called for aid to Gaza, Jayapal has emphasized her consistent and early calls for a cease-fire — so it would follow that groups like AIPAC would prefer that someone else wins. Tellingly, an analysis by Oregon Public Broadcasting found that a substantial portion of Dexter's last-minute donors have a history of giving to AIPAC, and some recently supported notable Republicans such as House Speaker Mike Johnson.

More controversially, The Intercept published reports in early May alleging that AIPAC funneled money to the 314 Action Fund to spend on Dexter's behalf, presumably because more direct intervention by AIPAC could backfire in a progressive-inclined district. The 314 Action Fund denied the allegations, and in the last pre-primary filing from the group on Monday evening, it turned out that a substantial chunk of the organization's recently raised cash came from billionaire former New York City Mayor Michael Bloomberg and financier Rob Granieri. Either way, the money could prove to be a massive difference-maker for Dexter's campaign.

Coming into today, we were tracking 31 people of color running for Congress in today’s primaries — 27 Democrats and four Republicans. With much of Georgia and Kentucky’s results in, we know the electoral fates of more than two-thirds of those contenders.

In Georgia, five incumbent Black Democrats all won renomination, including McBath, who cruised in the redrawn 6th District despite not previously representing any of this turf in her current district (the old 7th District). Scott didn’t have it as easy in the new 13th District, of which he only represents about one-third of right now, but he won the Democratic primary with 59 percent of the vote against a crowded field of challengers. Flowers, perhaps the most noteworthy of Scott’s opponents, finished in third with 10 percent. Democratic Reps. Sanford Bishop, Hank Johnson and Nikema Williams were all unopposed in their primaries.

Two other Black candidates have been projected as winners in Democratic primaries in solidly red Georgia seats. In the 8th District, Darrius Butler won his primary but will be a clear underdog against Republican Rep. Austin Scott. The same is true in the 12th District for Liz Johnson, who has to face GOP Rep. Rick Allen in November. On the GOP side, Latino contender Jonathan Chavez won the right to face Scott in the 13th District, which will almost certainly vote Democratic in November. And in the 4th District, Eugene Yu was unopposed for the GOP nomination; he’ll be a huge underdog against Johnson in the general election.

The remaining candidates of color with a shot at winning today are in Oregon, where we won’t have results for a while to come.

Here's something to do while waiting on those results ...

When it comes to winning elections, is it really, "the economy, stupid?" Are "soccer moms" the quintessential swing voter? And does it matter which candidate you'd rather share a beer with? Every election cycle, cliches come easy. But are they right?

That's what we try to get to the bottom of in our new mini-series on the 538 Politics podcast, "Campaign Throwback." In the first installment we interrogate the role that the economy plays in electoral outcomes, in the second we ask how suburban women came to be viewed as swing voters and whether that is the case today. In our final installment, which will come out tomorrow morning, we look at the "beer question." Starting in the 2000s, pollsters and pundits began speculating that voters are drawn to the candidate they'd rather have a beer with. We go back and look at the data to try to determine if that's actually how Americans choose their presidents.

So while you wait for that last set of polls to close, take some time to catch up on the latest "Campaign Throwback" episodes in the podcast feed, and tune back in tomorrow morning for our final installment!

Looking a little further down the ballot in the Peach State, Democrats are hoping they can reclaim the state legislative 56th District in Atlanta. Technically, Democrats won this seat in the last election, but state Rep. Mesha Mainor switched parties last year, after Democrats criticized her conservative stance on issues like school vouchers and policing.

Mainor is running unopposed in the GOP primary tonight, but four candidates are vying for the Democratic nomination, including 23-year-old public school math teacher Bryce Berry, who is currently leading with 55 percent, with half of the expected votes in. Berry has accumulated a decent war chest for a state House race, and has the endorsement of some high profile state Democrats, including House Democratic chairman Bill Mitchell and several local state Reps and state Senators, so it's not a total surprise to see him in the lead. If he wins the nomination tonight, he'll square off against Mainor in the fall to see if the Democrats can prevail despite no longer having the incumbent candidate.
