this practice, awarding two electors to the statewide winner and one to the winner in each congressional district. On the first Monday after the second Wednesday in December, about six weeks after the election, the electors convene in their respective state capitals (and in Washington, D.C.) to vote for president and, on a separate ballot, for vice president. They typically vote for the candidates of the party that nominated them. While there is no constitutional mandate or federal law requiring them to do so, the District of Columbia and 32 states have laws requiring that their electors vote for the candidates to whom they are pledged. The constitutionality of these laws was upheld in Chiafalo v. Washington (2020). Following the vote, each state then sends a certified record of their electoral votes to Congress. The votes of the electors are opened and counted during a joint session of Congress, held in the first week of January. If a candidate has received an absolute majority of electoral votes for president (currently 270 of 538), that person is declared the winner. Otherwise, the House of Representatives must meet to elect a president using a contingent election procedure in which representatives, voting by state delegation, with each state casting a single vote, choose between the top three electoral vote-getters for president. To win the presidency, a Candidate must receive the votes of an absolute majority of states (currently 26 of 50). There have been two contingent presidential elections in the nation's history. A 73–73 electoral vote tie between Thomas Jefferson and fellow Democratic-Republican Aaron Burr in the election of 1800 necessitated the first. Conducted under the original procedure established by Article II, Section 1, Clause3 of the Constitution, which stipulates that if two or three persons received a majority vote and an equal vote, the House of Representatives would choose one of them for president; the would become vice president. On February 17, 1801, Jefferson was elected president on the 36th ballot, and Burr elected vice president. Afterward, the system was overhauled through the Twelfth Amendment in time to be used in the 1804 election. A quarter-century later, the choice for president again devolved to the House when no candidate won an absolute majority of electoral votes (131 of 261) in the election of 1824. Under the Twelfth Amendment, the House was required to choose a president from among the top three electoral
