in a tie, which necessitated a contingent election in the House of Representatives. Under the terms laid out in the Constitution, the outgoing House of Representatives chose between Jefferson and Burr. Burr was accused of campaigning for the presidency himself in the contingent election despite being a member of Jefferson's party. Each state delegation cast one vote, and a victory in the contingent election required one candidate to win a majority of the state delegations. Neither Burr nor Jefferson was able to win on the first 35 ballots of the contingent election, as most Federalist representatives backed Burr and all Democratic-Republican representatives backed Jefferson. Hamilton favored Jefferson over Burr, and he convinced several Federalists to switch their support to Jefferson, giving Jefferson a victory on the 36th ballot. Jefferson became the second consecutive incumbent vice president to be elected president. Candidates Both parties used congressional nominating caucuses to formally nominate tickets for the first time. The Federalists nominated a ticket consisting of incumbent President John Adams of Massachusetts and Charles Cotesworth Pinckney of South Carolina. Pinckney had fought in the American Revolutionary War and later served as the minister to France. The Democratic-Republicans nominated a ticket consisting of Vice President Thomas Jefferson of Virginia and former Senator Aaron Burr of New York. Jefferson had been the runner-up in the previous election and had co-founded the party with James Madison and others, while Burr was popular in the electorally important state of New York.

On top of this, the election pitted the "larger than life" Adams and Jefferson, who were formerly close allies turned political enemies. The campaign was bitter and characterized by slander and personal attacks on both sides. Federalists spread rumors that the Democratic-Republicans were radical atheists who would ruin the country (based on the Democratic-Republican support for the French Revolution). In 1798, George Washington had complained "that you could as soon scrub the blackamoor white, as to change the principles of a professed Democrat; and that he will leave nothing unattempted to overturn the Government of this Country". Meanwhile, the Democratic-Republicans accused Federalists of subverting republican principles with the Alien and Sedition Acts, some of which were later
