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 to be a critical state, given its historical GOP loyalty, and campaigned in the state in October, arguing, to a severely hostile reaction, that America should use nuclear weapons in Vietnam.
