1800 United States presidential election
Before the Twelfth Amendment to the United States Constitution, the second place winner was the vice president. Because of this, Thomas Jefferson became John Adams' vice president even though they hated each other. This caused it to be an awkward time as the enemies had to work together. When the 1800 election rolled around, everyone was divided and furious. Adams had passed many unpopular laws like the Alien and Sedition Acts. John Adams was also called out for being too friendly with Britain, and his supporters responded by calling Jefferson supporters "Radical Atheists". This was the last election in America before the twelfth amendment was passed. There were technically two other people running, but they were more like vice presidential candidates. If electors supported one candidate, they were told to put their other vote to that candidate's unofficial vice president nominee, expecting that if they won, the other person would be in second place. John Adams' unofficial vice president candidate was Charles Cotesworth Pinckney, and Jefferson's was Aaron Burr.
