Thomas Jefferson Assumes the Office of the President of the United States of America

Working closely with Aaron Burr of New York, Jefferson rallied his party, attacking the new taxes especially, and ran for the Presidency in 1800.

Consistent with the traditions of the times, he did not formally campaign for the position. Prior to the passage of the 12th Amendment, a problem with the new union's electoral system arose. He tied with Burr for first place in the electoral college, leaving the House of Representatives (where the Federalists still had some power) to decide the election.

After lengthy debate within the Federalist-controlled House, Hamilton convinced his party that Jefferson would be a lesser political evil than Burr and that such scandal within the electoral process would undermine the still-young regime. The issue was resolved by the House, on February 17, 1801 after thirty-six ballots, when Jefferson was elected President and Burr Vice President. Burr's refusal to remove himself from consideration created ill will with Jefferson, who dropped Burr from the ticket in 1804 after Burr killed Hamilton in a duel.
