The electors who will ultimately cast votes for the President and Vice President are chosen in advance of the general election by political parties. Electors pledge to vote for the candidate from their party if that candidate wins the most votes in the state (or district in the case of Maine and Nebraska). "Faithless electors" are electors who ultimately vote for someone other than for whom they pledged.

Neither the U.S. Constitution nor federal statutes address the concept of "faithless electors." This issue is reserved to the states. A majority of states and the District of Columbia External have laws on the books that require electors to pledge to cast their votes for their parties’ nominees for President and Vice President. In July 2020, the United States Supreme Court held that a State may "penalize an elector for breaking his pledge and voting for someone other than the presidential candidate who won his State's popular vote." (Chiafalo v. Washington, No. 19–465, slip op. at 1-2 (July 6, 2020).) At the time the Supreme Court decided Chiafalo, fifteen states had laws imposing sanctions on electors for breaking their pledge to cast their vote for their party's nominee.

The opinion in Chiafalo provides a detailed background on faithless electors. For further information about faithless electors, researchers can consult these online resources:
