Pursuant to the 12th 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. In this event, the House is limited to choosing from among the three candidates who received the most electoral votes. Each state delegation votes en bloc, with each state having a single vote. A candidate is required to receive an absolute majority of state delegation votes (currently 26 votes) in order for that candidate to become the president-elect. The District of Columbia, which is not a state, does not receive a vote. The House continues balloting until it elects a president.
