Voters in Ohio will cast ballots on Tuesday to choose party nominees for federal and statewide offices. The election follows a mid-decade redistricting effort by the state legislature that redrawn congressional district boundaries in October 2025, reshaping the political landscape for House races across the state.

In the Republican gubernatorial primary, Vivek Ramaswamy and Casey Putsch are the leading candidates to replace term-limited Gov. Mike DeWine. Ramaswamy, who ran against President Donald Trump in the 2024 presidential race, received Trump's endorsement after announcing his gubernatorial bid in 2025. Trump wrote on social media that Ramaswamy "will be a GREAT Governor of Ohio" and has his "COMPLETE AND TOTAL ENDORSEMENT." Ramaswamy selected Ohio Senate President Rob McColley, who has served in the state senate since 2017, as his running mate.

Putsch, an entrepreneur, has centered his campaign on targeting diversity, equity, and inclusion programs as well as immigrant work visas, particularly the H-1B visa lottery system used to recruit high-skilled workers in technology and science sectors. Both Republican nominees will ultimately face Dr. Amy Acton, the sole Democratic candidate in the gubernatorial race.

In the U.S. Senate race, incumbent Jon Husted faces no Republican primary challenger. Husted was appointed to fill Vice President JD Vance's Senate seat and is seeking his first election to the chamber in a special election to complete Vance's term through 2028. On the Democratic side, former U.S. Sen. Sherrod Brown appears positioned as the frontrunner. Brown served nearly 20 years in the Senate before losing his seat to Republican Bernie Moreno in 2024. Brown has criticized Husted's voting record and proposed bans on congressional stock trading. He will compete against Rob Kincaid for the Democratic nomination. Kincaid has proposed a tax on artificial intelligence and automation companies, with revenues funding a monthly dividend for Ohioans.

In Ohio's first congressional district, Democrat Greg Landsman is defending his seat against three Republican challengers: Holly Adams, Eric Conroy, and Rosemary Oglesby-Henry. The new district boundaries now include traditionally Republican communities, making the race highly competitive. Conroy, an Air Force veteran and former CIA officer, has emphasized national security and American competitiveness.

Voters will also select candidates for secretary of state, treasurer, attorney general, and state legislative positions. Ohio maintains a Republican trifecta, with Republicans controlling the state senate, house, and governor's office. The state senate currently holds a 23-9 Republican majority while the House has a 65-34 advantage. Early voting ended Monday. Polls open Tuesday from 6:30 a.m. to 7:30 p.m.
