The 2012 United States presidential election in Ohio took place on November 6, 2012, as part of the 2012 United States presidential election in which all 50 states plus the District of Columbia participated. Ohio voters chose 18 electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan. This election continued Ohio's bellwether streak, as the state voted for the winner of the presidency in every election from 1964 to 2016.
