The election of 1800 saw incumbent John Adams go back up for re-election. This time both parties were mad at each other. Both the Federalists and the Democratic-Republicans both threw baseless claims at one another.
John Adam's running mate was Charles Cotesworth Pinckney who was the former United States Minister to France.
Thomas Jefferson came back from defeat and went up for election again.
His running mate was Aaron Burr
Jefferson/Burr managed to beat the Adams/Pinckney ticket with 61% of the vote. Electoral votes were closer with Jefferson winning 73 vs Adam's 65.
