ABC News has projected Moreno will win the GOP primary for Senate in Ohio, setting up a clash with three-term incumbent Sherrod Brown this fall. Moreno was endorsed by Trump, but also benefitted from spending by a Democratic super PAC that viewed him as a weaker general election opponent than the man he beat, state Sen. Matt Dolan.

Let's check in on how Trump's three endorsed candidates are doing tonight! As it turns out, all three are currently leading their races (though we're just now getting the very first results from Illinois's 12th District, so take that one with a grain or ten of salt).

The Associated Press has called the GOP Senate primary in Ohio for Moreno, though ABC News has not yet made a projection. He currently leads with about 42 percent of the vote, and 25 percent of the expected vote reporting.

Cooper, I wonder how much the potential threat of limiting abortion access in Ohio could impact that Supreme Court race. In 2023, voters in the state passed a constitutional amendment protecting abortion access. In a sign that abortion may continue to be an issue that divides Republican-leaning voters, a November Emerson College/WJW-TV/Nexstar survey conducted just after that election asked registered Ohio voters how they voted on the abortion measure and how they plan to vote in November this year.

Twenty-six percent of those who voted to pass the abortion rights measure said they plan to vote for Donald Trump, suggesting that a fair number of Republican or Republican-leaning voters supported it. (In comparison, just 10 percent of those who voted against the measure said they planned to vote for Joe Biden.) Abortion also seemed to drive turnout among Democratic-leaning voters in last November's election: Among those that said they voted on the abortion referendum (either for or against), 41 percent said they'd vote for Biden, while only 28 percent of those who didn't vote supported Biden. (About half of both 2023 voters and nonvoters supported Trump.)

So if the issue of abortion becomes salient in the state Supreme Court race, there could be a close race coming our way in November.

It’s midnight Eastern, and all but one of our key races have been projected in Ohio and Illinois. Here’s a recap of where things stand in those races:

- Former President Donald Trump once again flexed his muscles in the Ohio Senate race, elevating former car salesman Bernie Moreno from a 2022 also-ran to the GOP nominee in one of the two top Senate races on the map, beating an uber-rich state senator and a two-time statewide officeholder in the process. But Moreno’s toughest path lies ahead, against well-funded incumbent Democratic Sen. Sherrod Brown. With 96 percent of the expected vote reporting, Moreno leads with 51 percent of the vote over state Sen. Matt Dolan’s 33 percent and Ohio Secretary of State Frank LaRose’s 17 percent.

- In Ohio's 9th District, the conservative backed by Trump and House Speaker Mike Johnson, state Rep. Derek Merrin, is projected to win, and ready to take on Democratic Rep. Marcy Kaptur in what could be a tough general election race. With 80 percent of the expected vote reporting, Merrin has won 52 percent of the vote, 18 percentage points ahead of his nearest competition.

- In Ohio’s 13th District, another potentially competitive Democratic-held seat, former state Sen. Kevin Coughlin advanced out of the GOP primary rather easily and will take on Democratic Rep. Emilia Sykes in November. With 80 percent of the expected vote in, Coughlin leads with 65 percent of the vote so far over businessman Chris Banweg’s 28 percent and Richard Morckel’s 7 percent.

- The Republican Main Street Partnership notched a win against its rivals in the House Freedom Caucus in Ohio’s 6th District, where state Sen. Michael Rulli is projected to beat state Rep. Reggie Stoltzfus. Rulli currently leads by 9 points with 83 percent of the expected vote reporting in the regular primary, and by 8 points with 82 percent of the expected vote in the special election. Rulli will face a nominal challenge from Democrat Michael Kripchak on June 11 in the special election to replace Rep. Bill Johnson.

- In another safe GOP seat, Ohio’s 2nd District Republican primary went for business owner David Taylor, who won a crowded race that was tantamount to election in November. With 95 percent of the expected vote reporting, Taylor leads with 25 percent of the expected vote over 10 other challengers.

- Despite several challengers lining up to replace Democratic Rep. Danny Davis, the long-time incumbent is likely to hold onto his seat in Illinois’s 7th District. With 76 percent of the expected vote in, Davis leads with 53 percent of the vote so far. In second is Chicago City Treasurer Melissa Conyears-Ervin with 22 percent, followed by community organizer Kina Collins with 18 percent. Collins was seen as Davis’s primary competition tonight, and her underwhelming performance was part of a tough night for progressives in Chicago.
