Explanation: Democratic-Republican Thomas Jefferson defeated Federalist John Adams by a margin of seventy-three to sixty-five electoral votes in the presidential election of 1800. When presidential electors cast their votes, however, they failed to distinguish between the office of president and vice president on their ballots. Constitution did not distinguish between President and Vice-President in the votes cast by each state's electors in the Electoral College, both Jefferson and his running mate Aaron Burr received 73 votes. Many Federalists saw Jefferson as their principal foe, whose election was to be avoided at all costs.
