Though Trump has already clinched the 2024 Republican presidential nomination, many states have yet to vote in their party primary. Political observers have been closely watching Trump's margins in these states for any potential signs of weakness with his base ahead of the general election. While many who vote against Trump in the primary probably weren't going to vote for him in the general election anyway, former U.N. Ambassador Nikki Haley, who dropped out of the presidential race in March, has routinely been garnering between 15 and 20 percent of the vote in primaries since then, a potential sign of dissatisfaction with Trump among some Republicans.

Whether or not you think that means trouble for Trump in November, he's not having that problem in Kentucky tonight: With 72 percent of the expected vote in, the former president is currently winning 85 percent of the vote, while Haley is at just 6 percent.

Two of the four anti-abortion Republican candidates we've been tracking in Kentucky are projected to win their races, according to The Associated Press. Incumbents Guthrie and Massie prevailed against their challengers, while Edwards lost to incumbent Rogers.

In Georgia, Yu, McCormick, Scott, Clyde, Collins, and Greene were uncontested in their respective districts. In the 11th District Republican primary, Loudermilk is projected to defeat his challenger. With just over half the expected vote reporting, he has 88 percent of the vote.

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.

It’s only 8 p.m. Eastern, and yet 40 percent of the statewide vote is reporting in Georgia and we have a pretty good feel for where these races are headed. That could be a good sign for November, when Georgia will obviously be one of the most closely watched states in the nation. A clear winner here early-ish on election night would do a lot to avoid a repeat of 2020, when a winner wasn’t projected until the Saturday after the election. (And yes, I’m still traumatized from that.)

With all of tonight's key races now projected, it's time for us to hit the hay. Here's a recap of who won today:

- Despite trying to ride the wave of voter activation over abortion, former Democratic Rep. John Barrow failed to unseat Republican-appointed Justice Andrew Pinson in the only contested race for Georgia Supreme Court today.

- Challenges to a pair of major figures in Trump's Georgia election-interference case also went nowhere. Fulton County District Attorney Fani Willis easily won her Democratic primary, and Judge Scott McAfee won his judicial election against a self-described "conservative Democrat."

- The Republican primary in Georgia's 3rd District is going to a June 18 runoff between longtime Trump staffer Brian Jack and former state Senate Majority Leader Mike Dugan.

- In Georgia's 13th District, incumbent Rep. David Scott prevailed over his six challengers to win his Democratic primary and will go on to seek reelection in November. Scott's challengers tried to focus on his age and health as an issue, echoing criticisms facing the Democrats and President Joe Biden in November, but incumbency proved too powerful an advantage.

- Out west, the DCCC got their candidate in Oregon's 5th District, as state Rep. Janelle Bynum easily dispatched attorney Jamie McLeod-Skinner, who lost in 2022 in this seat against Republican Rep Lori Chavez-DeRemer. Bynum will face off against Chavez-DeRemer this November.

- In Oregon's 3rd District, state Rep. Maxine Dexter benefited from a plethora of outside spending to defeat former Multnomah County Commissioner Susheela Jayapal in the Democratic primary, all-but-ensuring that Dexter will be this dark-blue seat's next representative.

- Republican Mike Erickson will get a third shot at winning a House seat as he cruised to victory in the GOP primary for Oregon's 6th District. At times, Erickson seems more focused on winning a defamation case against Rep. Andrea Salinas regarding an ad she aired last cycle against him than he does on beating her in an election.

- In Idaho's 2nd District, incumbent Republican Mike Simpson is poised to win his primary and likely reelection this fall. With more than 60 percent of the votes counted, he leads his closest challenger, investment adviser Scott Cleveland, 57 percent to 34 percent. (Scott Cleveland is a great quarterback name, now that this politics thing doesn't seem to be working out.)

- In the special election in California's 20th District (former Speaker Kevin McCarthy's old seat), Assemblyman Vince Fong defeated fellow Republican Tulare County Sheriff Mike Boudreaux. As a result, Speaker Mike Johnson will soon get an extra vote in the House.
