When did Thomas Jefferson win the presidential election of 1800?

Answer 1

Thomas Jefferson won the 1800 presidential election defeating John Quincy Adams, Aaron Burr, Charles Pinckney, and John Jay. In 1800 electors voted for two individuals and did not distinguish between their presidential and vice-presidential choices until the passage of the Twelfth Amendment to the United States Constitution in 1803. The recipient of the most electoral votes in 1800 would become president and the runner-up vice-president. Thomas Jefferson received 73 electoral votes, his running-mate Aaron Burr received 73 electoral votes, John Quincy Adams received 65 electoral votes, Charles Pinckney received 64 electoral votes, and John Jay received 1 electoral vote. Although John Quincy Adams ran as Thomas Jefferson's main opponent in the general election, running-mates Thomas Jefferson and Aaron Burr received the same number of electoral votes. The election was decided in the House of Representatives, with 10 State delegations voting for Jefferson, 4 voting for Burr and 2 making no choice. Thomas Jefferson became President and his running-mate Aaron Burr became Vice President.

Answer 2

The election was not decided until February 1801 when the House of Representatives finally chose Jefferson over Aaron Burr after 36 ballots (the two had been tied in electoral vote, 73-73).
