In the Presidential election of 1800, Thomas Jefferson runs for President and Aaron Burr for Vice President on the Democratic-Republican ticket. Both get 73 votes in the Electoral College. This forces the election into the House of Representatives, where the Federalist Party holds the majority. Opposition to Jefferson causes many Federalists to vote for Burr. Repeatedly casting ballots, the House is unable to reach a majority for any candidate until former treasury secretary Alexander Hamilton intervenes with Federalists and persuades them to vote for Jefferson on the thirty-seventh ballot. This event spurs demand for the Twelfth Amendment.
