1872 United States presidential election in Ohio

The 1872 United States presidential election in Ohio was held on November 5, 1872, as part of the 1872 United States presidential election. State voters chose 22 electors to the Electoral College, who voted for president and vice president.

Ohio was won by the Republican Party candidate, incumbent president and Ohio native Ulysses S. Grant, who won the state with 53.24% of the popular vote. The Democratic and Liberal Republican Party candidate, Horace Greeley, garnered 46.15% of the popular vote.

Seeing as it was unlikely they could pull off a victory in the general election, the Democratic Party endorsed the Liberal Republican candidate Horace Greeley, who had been involved in a split from the traditional Republican Party. A New Yorker, Greeley had been nominated in Cincinnati, Ohio, at the 1872 Liberal Republican convention.

The other two candidates who garnered votes in Ohio during the election were James Black, a member of the Prohibition Party, and Charles O'Conor, a straight-out Democrat. Black and the prohibitionists were dedicated to the outlaw of alcohol, while O’Conor and the straight-out Democrats ran dissatisfied with the Democratic nomination of Greeley.
