Ohio Primary Elections 2026: Key Races, Candidates, and What to Watch
Ohio voters head to the polls Tuesday in a high-stakes primary that could shape the political landscape ahead of November’s midterm elections. With crucial races for governor, U.S. Senate, and House seats, the outcomes will set the stage for a fierce battle over control of Congress and state leadership.
High-Profile Governor’s Race
The Republican primary for governor pits tech entrepreneur and former presidential candidate Vivek Ramaswamy against auto racing engineer Casey Putsch. Ramaswamy, backed by former President Donald Trump and the Ohio GOP, holds a massive financial advantage, having poured $25 million of his own money into the race. Putsch, meanwhile, has struggled to keep pace, raising just $123,000.
The winner will face Dr. Amy Acton, the unopposed Democratic nominee. Acton, Ohio’s former health director during the COVID-19 pandemic, resigned in 2020 amid political pressure but remains a prominent figure in state politics.
A third GOP candidate, Heather Hill, was disqualified after her running mate dropped out, though her name will still appear on ballots—votes for her won’t count.
Battle for the Senate
Democrats are banking on former Sen. Sherrod Brown to reclaim his seat in a race critical to their hopes of flipping the Senate. Brown, who lost to Republican Bernie Moreno in 2024, faces little competition in the primary against Ron Kincaid.
On the Republican side, incumbent Sen. Jon Husted—appointed after JD Vance became vice president—faces no primary challengers. The general election will be a major test of Ohio’s shifting political loyalties.
House Races to Watch
In Ohio’s 9th Congressional District, a crowded GOP field is vying to challenge Democratic Rep. Marcy Kaptur, the longest-serving woman in House history. Kaptur narrowly survived a tough 2024 race against Republican Derek Merrin, who’s running again.
Merrin faces competition from Madison Sheahan, a former ICE official, and state Rep. Josh Williams, among others. The district, which includes Toledo, could be a bellwether for broader Republican gains in the Midwest.
Election Logistics
- Polls close at 7:30 p.m. ET.
- Automatic recounts kick in if margins are under 0.25% (statewide) or 0.5% (House races).
- Over 275,000 early ballots have already been cast.
- Ohio allows open primaries: Voters can choose either party’s ballot but will be affiliated with that party afterward.
Why Ohio Matters
With 7.9 million registered voters, Ohio remains a pivotal swing state. Trump swept every county in the 2024 GOP primary, and his endorsement could sway undecided voters. Democrats, meanwhile, hope to capitalize on suburban shifts and Acton’s public health credentials.
As results roll in Tuesday night, all eyes will be on early vote tallies—typically released shortly after polls close—for clues on which candidates have momentum.
The road to November starts here.
