Thomas Jefferson (Democratic-Republican) defeated John Adams (Federalist) in the presidential election of 1800 by an electoral vote of seventy-three to sixty-five. However, because electors could not distinguish between president and vice president when voting prior to the Twelfth Amendment (1804), Jefferson and his running mate, Aaron Burr, received the same number of votes in the Electoral College. With the vote tied, the presidential election was then decided by the House of Representatives as stipulated in Article II, Section 1, of the U.S. Constitution. After thirty-six ballots, the Federalist-controlled House finally elected Thomas Jefferson president on February 17, 1801.
