Polls show a close race in the GOP primary for Ohio Senate
Democrats (and allied independents) currently hold a bare majority in the U.S. Senate, with 51 seats to Republicans’ 49. But control of the chamber is at stake in November, and the Senate race in Ohio is one of a few competitive contests that could decide control of the chamber.
Three Republican contenders are facing off today for a chance to challenge incumbent Democrat Sherrod Brown in that contest: Matt Dolan, a state legislator running with the endorsement of former Ohio Sen. Rob Portman; Frank LaRose, the current Ohio Secretary of State running on a campaign of conservatism and electability; and Bernie Moreno, a businessman with endorsements from Trump, a dozen members of Congress including Ohio Sen. J.D. Vance and the Club for Growth PAC, one of the oldest conservative PACs in the country.
Moreno, who appeared alongside Trump in several campaign events this past weekend, has gained significant ground in the polls since the former president endorsed him in mid-December. Then, he was polling at 16 percent in 538’s polling average — and now he’s hovering in the mid- to-high-20s. Democrats view Moreno as the weakest candidate for the general election and last week began airing a television ad intended to boost his standing by “attacking” his conservative record and support for Trump ahead of Tuesday's primary.
But the polls show a tied race between Dolan and Moreno, who each lead LaRose by 10 percentage points. That’s too close for polls to provide a reliable signal of who is decisively leading: Per our database of historical polls, surveys of Senate primaries miss the margin between the winner and runner-up by 6.5 points on average.
Looking ahead to the general election, the winner of today’s Republican primary matters not just in deciding who might be Ohio’s next senator, but in deciding control of the Senate come 2025. Since West Virginia Democratic Sen. Joe Manchin decided to retire, prognosticators largely expect the Republicans to pick up at least one seat this November. That means Democrats and Republicans start their fight for the majority from a 50-50 tie, and Democrats need to at least hold on to the rest of their endangered seats — and for Biden to win — to maintain control.
Ohio is a red state, but Brown has managed to run ahead of expectations in previous cycles. So has fellow endangered Democrat, Montana Sen. Jon Tester. But neither of them have run in a presidential cycle since 2012, when President Barack Obama pulled off a surprising reelection and Democrats gained two seats in the Senate. Brown will face not just the strength of his opponent in November, but the partisanship of his constituents. The Cook Political Report rates the Ohio Senate race a toss-up.
