The 1964 United States presidential election in Indiana took place on November 3, 1964, as part of the 1964 United States presidential election. State voters chose 13 representatives, or electors, to the Electoral College, who voted for president and vice president. Republican candidate Barry Goldwater naturally considered Indiana critical given its GOP loyalty and campaigned in the state during October, when he argued to a severely hostile reaction that America should use nuclear weapons on Vietnam.
