In the Ohio Senate race, Moreno leads Dolan 40 percent to 37 percent with 21 percent of the expected vote reporting, but I'd make him a stronger favorite than that close margin suggests. Much of the vote tallied so far is from early and absentee votes, which are probably more favorable to Dolan. We've seen in previous elections that votes cast on Election Day tend to be better for more Trump-aligned candidates, which should benefit Moreno as Ohio starts to count more of those votes. For instance, around this hour of the evening in Ohio's 2022 Senate primary, Vance led with a tad less than 28 percent with a similar share of the vote reporting, but he wound up winning with 32 percent. That was a more crowded race, but you'd rather be Moreno at this point than Dolan.

With just a shade under 20 percent of the expected vote counted in Ohio's 6th District, state Sen. Michael Rulli leads state Rep. Reggie Stoltzfus by 7 percentage points in the regularly scheduled primary and 6 points in the special election. Rulli's massive lead in his home base, Mahoning County, is giving him the early advantage.

In the only contested Ohio Supreme Court primary today, Democratic 8th District Court of Appeals judge Lisa Forbes is up 64 percent to 36 percent over former public defender Terri Jamison with 26 percent of the expected vote in, according to the Associated Press. The winner will face Republican judge Dan Hawkins, who ran unopposed today, in November to fill the now-open seat of Republican Justice Joe Deters.

The current state Supreme Court is made up of three Democrats and four Republicans. Two of those Democratic justices are up for reelection, alongside Deters's seat. Deters is still running in November, but against his colleague, Democratic Justice Melody Stewart, for different seat on the court. If either Forbes or Jamison can flip Deters's old seat and Democrats can hold on to their other two incumbents, they would gain control of the state's highest court. That seems unlikely though, given Ohio's Republican lean and the results of recent Supreme Court elections in the state.

You didn’t think we’d forget, did you, dear reader? In Florida, Illinois and Ohio, ABC News is projecting that Trump and Biden have won their primaries.

Democrats are likely to be pleased with the Moreno win in the GOP primary for Ohio's Senate seat tonight. Because of his ideological extremity and endorsement from Trump, most Democratic strategists and political prognosticators believe him to be a weaker general-election candidate than his competitors would have been. Indeed, Democrats even took out ads in favor of Moreno, trying to boost him to exactly this outcome.

This is not a completely baseless idea. After the 2022 midterms, I found that GOP primary candidates who were endorsed by Trump went on to lag the predictions for general-election Democratic by a vote margin of about 5 percentage points. That large of an effect could tip a close race in Ohio, so the expected vote calculus likely favors Democrats here.

But the political calculus is another matter. Democrats have been criticized in the past for endorsing Trump's chosen candidates as an electoral strategy on the grounds that it increases the likelihood of Washington passing Republican policies and pushing Trump's agenda. Given that the Senate is likely to go Republican in the fall, having Trump-endorsed Moreno in the halls of Congress may provide a higher ROI for Trump than having a Senator Dolan or LaRose. By pushing these ads, Democrats are betting the return on votes will outweigh the potential downside. That bet does not come without risk.
