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.

In the Ohio House of Representatives, a speaker battle from last year is playing out in the GOP state legislative primaries tonight.

Republicans have veto-proof majorities in both chambers. But when it came time to elect a speaker at the start of the term last year, a moderate Republican, state Rep. Jason Stephens, beat a far-right candidate, Derek Merrin, in a surprising upset thanks to backing from the chamber’s Democrats and 22 Republicans (including Stephens himself). As speaker, Stephens has control over which bills make it to the floor, and Democrats backed him in exchange for support on some of their policy priorities. Meanwhile, the conservative wing of the party censured those 22 members, dubbing them the “Blue 22.”

This year, Merrin himself is term-limited and running in the 9th Congressional District , while the conservatives who backed him for speaker are now backing challengers against half of the pro-Stephens Republicans. National groups have also stepped in to back these challengers, telling the Statehouse News Bureau that they don't want to just elect Republicans; they also want to support a "bold conservative policy agenda." Adding yet another dynamic to the conflict, the current state Senate President Matt Huffman, a conservative who is also term-limited in the Senate, has jumped into the fray and is running unopposed for a state House seat. He has signaled that he wants to be speaker, and donated to the incumbents who backed Merrin in the speaker fight.

The tug-of-war between the far-right and more moderate members of the Republican Party is playing out in states around the country, and, in some cases, among far-right members themselves. Some of the infighting is centered over what happened in 2020 and the false claim that Trump actually won, and could seriously weaken the state parties heading into competitive general election contests in states like Michigan, Arizona and Georgia. In safe-red Ohio, the consequences could be more localized, but the speaker race, for example, will have a major impact on the kinds of bills the state legislature tries to pass next year around divisive issues like abortion or redistricting.
