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.

One under-the-radar race today is the Republican primary in Ohio’s 2nd District, which is tantamount to that seat’s general election given how red this seat is. Eleven Republicans are vying to replace retiring Rep. Brad Wenstrup, but three businessmen have used their wallets to stand out from the crowd. Concrete business owner David Taylor has loaned his own campaign $1.7 million, while Larry Kidd, who owns a hiring agency, has invested $1.3 million in the race. Meanwhile, Dunkin’ Donuts and LaRosa’s Pizzeria franchisee Tim O’Hara has spun up the third-most dough after self-funding $1.2 million.

Two state legislators are also running. State Sen. Niraj Antani has raised a respectable $671,000, but his district doesn’t overlap at all with the 2nd District, according to Daily Kos. State Sen. Shane Wilkin, by contrast, already represents 33 percent of the 2nd District, but he has raised only $146,000. If we had to pick a favorite here, it would probably be Taylor given that he has the most money and he’s the only major candidate from Clermont County, by far the most vote-rich county in the district. There are no runoffs in Ohio, so whoever finishes first in the primary will become the nominee even if they win just a bare plurality.
