The United States presidential election of 1800,…
December 1800 CE
In what is sometimes referred to as the "Revolution of 1800", Vice President Thomas Jefferson of the Democratic-Republican Party defeatsincumbent President John Adams of the Federalist Party.
The election is a realigning election that ushers in a generation of Democratic-Republican rule.
At the end of a long and bitter campaign, Jefferson and Burr have each won seventy-three electoral votes, Adams has won sixty-five electoral votes, and Pinckney has won sixty-four electoral votes.
The Federalists sweep New England, the Democratic-Republicans dominate the South, and the parties split the Mid-Atlantic states of New York, New Jersey, and Pennsylvania.
The Democratic-Republicans' failure to execute their plan to award Jefferson one more vote than Burr results in a tie, which necessitates a contingent election in the House of Representatives.
Under the terms laid out in the Constitution, the outgoing House of Representatives chooses between Jefferson and Burr.
Each state delegation casts one vote, and a victory in the contingent election requires one candidate to win a majority of the state delegations.
Neither Burr nor Jefferson are able to win on the first thirty-five ballots of the contingent election, as most Federalist Congressmen back Burr and all Democratic-Republican Congressmen back Jefferson.
Hamilton personally favors Jefferson over Burr, and he persuades several Federalists to switch their support to Jefferson, giving Jefferson a victory on the thirty-sixth ballot of the contingent election.
The result of this election is affected by the three-fifths clause of the United States Constitution; historians such as Garry Wills have noted that had slaves not been counted for the purposes of congressional apportionment, Adams would have won the electoral vote.
