The US presidential election of 1800 is most remembered because of the controversy it went through. This election was mostly based on domestic affairs and foreign affairs played a negligible or no part at all. The two presidential candidates, Jefferson and Aaron Burr were tied with 73 ballots in their favour. John Adams the Federalist got 65 Electoral votes in his favor. Later during the 36th ballot in the House of Representatives Jefferson won and became president. Aaron was chosen the Vice President. So both the winner and loser were satisfied.
