The 2064 United States presidential election in Colorado took place on November 4, 2064, as part of the 2064 General Election in which all 52 states and the District of Columbia participated. Colorado voters chose 18 electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President William J. Rutherford and his running mate, Vice-President Carlotta A. Sanchez, against Republican challenger and South Dakota Governor Thomas P. Leach and his running mate, Congressman Marty Daniels. President Rutherford easily won his home state over Governor Leach, capturing 73.25% of the vote, versus 26.75% for Leach, a margin of 46.50%. The President overperformed his national total in Colorado, winning all 64 of its counties (as had been the case in 2060). This made him the first candidate since Warren G. Harding in 1920 to win all of Colorado's counties, and the first Democrat ever to accomplish this feat.
