Ohio Political History & Voting Patterns
Ultimate bellwether until 2016; now lean-R. A complete guide to how Ohio has voted in presidential elections, which coalitions have driven results, and how the state has shifted over time.
Historical Overview
Ohio was the ultimate swing state for most of the 20th century and early 21st — deciding the 2004 election, won by Obama twice, and then reversing sharply. Trump’s 2016 win by 8 points — far exceeding expectations — signaled Ohio’s departure from true swing-state status. Sherrod Brown was the last Democrat to win a statewide race, holding on through three cycles before losing in 2024. Ohio’s Rust Belt cities (Cleveland, Columbus, Akron, Dayton, Cincinnati) produce Democratic votes, but exurban and rural Ohio has moved sharply right. Columbus (Franklin County) is the exception, growing into a major Democratic stronghold.
