In Kentucky, each county can determine whether to allow alcohol sales, and to what degree. In the 2023 general election, several counties approved the sale of alcohol after having been dry for decades. Tonight, after 3 previous failed attempts, a small southeastern Kentucky county finally voted to approve liquor sales. Cheers, Knott County.

Polls close in part of Idaho in about a half an hour, but the only race we're really watching there is the GOP primary in the 2nd Congressional District. Republican Rep. Mike Simpson has represented the solidly red seat since first winning it in 1998, and he seems more likely than not to claim a 14th term in Congress this year. However, Simpson's relatively centrist brand has previously caused him trouble, like in 2022 when he only won 55 percent against a well-funded primary challenger.

Now, Simpson doesn't have the same scale of opposition this time around: His main competitor is Scott Cleveland, an Ada County (Boise) GOP central committee member running to Simpson's right who's only raised $100,000. Still, we're keeping an eye on Simpson's vote share because some establishment Republicans this cycle have had weak primary performances against more right-wing challengers, like Arkansas Rep. Steve Womack and Texas Rep. Tony Gonzales (who still has to face his challenger again in a May 28 runoff).

With 62 percent of the expected vote in, incumbent Georgia Rep. Scott has 61 percent of the vote so far, according to The Associated Press. His closest challenger, Baker, a former city council member who lost to Scott in 2022, is at 11 percent.

Matt Klein, from the Cook Political Report with Amy Walter, reminds us that before reinventing himself as a crusader for abortion rights in this year's election, Barrow was a conservative Blue Dog Democrat in Congress:

Hard to come up with a better illustration of the old way to win elections as a Democrat in the Deep South vs. the new way!

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.
