Illinois and Ohio primaries 2024: Trump-backed Senate candidate wins Ohio primary

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.
