Illinois and Ohio primaries 2024: Trump-backed Senate candidate prevails in Ohio primary
538 tracked key House and Senate races, including a California special election.
November’s presidential matchup may be set, but Democrats and Republicans still need to decide who will run in hundreds of downballot races (e.g., for Senate and House) this fall. A batch of these contests were decided on Tuesday, March 19.
Tuesday was primary day in Ohio and Illinois, and in the biggest contest of the day, Republicans chose former President Donald Trump's endorsee Bernie Moreno as their candidate in Ohio’s U.S. Senate race. It was a good night for other Trump endorsees too, as Derek Merrin prevailed in the GOP primary for Ohio's 9th Congressional District, while incumbent Mike Bost is leading his challenger in Illinois's 12th District, as of early Wednesday morning. Plus, a special election in California could have immediate implications for House Republicans’ razor-thin majority.
538 reporters and contributors broke down the election results as they came in with live updates, analysis and commentary. Read our full live blog below.

ABC projects Moreno to win
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.

Trump's having a good night so far
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 AP has called for Moreno
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.

Abortion may motivate Ohio Democrats
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.

Ohio 6’s special election turns negative
The special election to replace former Rep. Bill Johnson in Ohio’s 6th District has been a relatively low-key affair since the seven-term Republican left office in January. State Sen. Michael Rulli and state Rep. Reggie Stoltzfus are both running in the regularly scheduled primary and the special election primary for the GOP nomination tonight (so is chiropractor Rick Tsai, who has not raised much money and isn’t seen as a contender); the winner will be a shoo-in for both the June 11 special general election and November general election in this safe red district.
Both candidates are tying themselves closely to Trump, and spent the first month of the race airing positive ads. But Rulli, who is backed by the U.S. Chamber of Commerce, once had a more moderate reputation in the state Senate when he represented a competitive Youngstown-area seat, while Stoltzfus, who has backing from the socially conservative Family Research Council and Gen. Mike Flynn, has consistently been one of the most conservative members of the state House and has pledged to join the House Freedom Caucus if elected.
In the closing weeks, the race has turned on LGBTQ issues, with Stoltzfus airing ads accusing Rulli of “sponsoring legislation to allow boys in girls’ bathrooms” — a reference to Rulli’s cosponsorship of an LGBTQ anti-discrimination bill (he was one of the only Republicans to back the bill). Rather than lean into his record, Rulli’s allies at Defending Main Street (a wing of the Republican Main Street Partnership) are working to fashion the candidate, who once described himself as “really pro-gay rights” into a conservative outsider who “will stop the Left’s war on children” with respect to transgender issues.
Stoltzfus ($492,000) and Rulli ($479,000) have spent around the same amount of money on ads through March 18, per AdImpact data, with the pro-Rulli Defending Main Street PAC chipping in another $80,000.
