Elections inOhio are held on a county, state, and federal level. The Republicans are strongest in the rural Northwest, the affluent Cincinnati and Columbus suburbs, and have made gains in Appalachian Southeast Ohio and the industrial, working-class Northeast in the 21st century. The Democrats rely on the state's major cities, and have made gains in educated suburban areas in recent years.
The state was strongly Republican from the party's inception, as it voted Republican in every election from 1856 to 1908. The northern Union-aligned part of the state kept the state Republican, and consistently narrowed edged out the Democratic and Appalachia-influenced southern Ohio. Since 1896, however, Ohio has voted for the winning candidate, except for Franklin D Roosevelt in 1944, John F Kennedy in 1960, and Joe Biden in 2020. This was due to Democratic gains in the northeastern part of the state. The state has not backed a losing candidate in consecutive elections since 1848. Due to a close split in party registration, it has been keybattleground state. No Republican has ever been elected president without winning Ohio. In2004, Ohio was the tipping point state, as Bush won the state with 51% of the vote, giving him its 20 electoral votes and the margin he needed in theElectoral College for re-election. The state was closely contested in 2008 and 2012, withBarack Obama winning narrowly on both occasions. Ohio has been abellwether state in presidential elections.
Since 2016, Ohio's bellwether status has been questioned given that Donald Trump won it by 8 points, the largest margin for each party since 1988, and then won the state by a similar margin in 2020 despite losing nationwide.[2][3]
In a 2020 study, Ohio was ranked as the 17th hardest state for citizens to vote in.[4]
In the leadup to the 2020 Ohio elections, by February 2020, eight Ohio counties had failed to complete an election security checklist required by Ohio's top election official. One county, Van Wert County Board of Elections, was placed on administrative oversight because it provided no plan for complying with the directive.[5]
