Faithless elector
A faithless elector in the United States Electoral College is a designated presidential elector who casts a vote for a candidate for President or Vice President other than the one pledged under state party rules or law, typically the nominee who secured the state's popular vote.[1][2] Electors, selected by popular vote in each state, formally convene to cast ballots that determine the presidential outcome, but the Constitution grants them discretion absent state enforcement mechanisms.[3] Though faithless voting has occurred sporadically since the nation's founding—totaling fewer than 200 instances amid over 20,000 elector votes cast, with no instance altering a presidential election result—such deviations have spurred legislative responses in 33 states and the District of Columbia, including fines, pledge requirements, or automatic replacement of noncompliant electors.[4][5] In a unanimous 2020 decision, Chiafalo v. Washington, the Supreme Court held that the Constitution permits states to bind electors to their pledge or penalize faithlessness, resolving prior uncertainties and reinforcing state authority over the process without violating federal electoral provisions.[6][7] This ruling addressed challenges from electors fined for defecting in 2016, affirming that historical practice and textual interpretation support state control to ensure alignment with voter intent.[6] Debates over elector independence persist, yet empirical rarity underscores the system's stability against such disruptions.[4]
