Declared candidates. OPEN seat: incumbent Gov. Mike DeWine (R) is term-limited (no third consecutive term). Vivek Ramaswamy won the Republican primary (Trump-endorsed; only nominal opposition). Former Ohio Dept. of Health director Amy Acton won the Democratic primary unopposed. Earlier-speculated Democrats Tim Ryan and Sherrod Brown did not run. The field and its fundraising will keep updating as primaries settle and new FEC reports land.
The rating is grounded in this seat’s record on Akashic — its partisan lean, same-office history, and demographics. Read the full profile on the OH state page.
