Ohio was won by Trump by a margin of 8.07 points. Prior to the election, most news organizations considered Ohio as leaning Republican, due to Trump's appeal to blue-collar voters in the Rust Belt. Ohio kept its streak of voting for the winner as a bellwether state since 1964, as it voted for Trump, who won nationally. Having previously voted Democratic in 2012 and 2008, the winning margin was the second largest of the states Trump flipped red, after Iowa. It also marked the largest margin of victory since George H. W. Bush defeated Michael Dukakis in the state in 1988.
Additionally, Trump became the first Republican to win the presidency without carrying Hamilton County since Rutherford B. Hayes in 1876. Ohio was 10.2% more Republican than the national average in 2016, the farthest it had voted from the rest of the nation since 1932. Like all of its neighboring states except for longtime Republican state Indiana, Ohio was one of eleven states to vote for Bill Clinton twice in 1992 and 1996, only to be lost by Hillary Clinton in 2016.
As of 2024, this is the most recent time the Democratic candidate won either Lorain County or Mahoning County and the most recent time the Republican candidate won Montgomery County.
