How many electoral votes are needed to win? What happens if there is a tie in the Electoral College?

A candidate must receive an absolute majority of electoral votes (currently 270) to win the presidency or the vice presidency. If no candidate receives a majority in the election for president or vice president, the election is determined via a contingency procedure established by the Twelfth Amendment. The House of Representatives is required to go into session immediately after the counting of the electoral votes to vote for president if no candidate for the office receives a majority of the electoral votes.
