Ranked-choice voting (RCV) can refer to one of several ranked voting methods used in some cities and states in the United States. The term is not strictly defined, but most often refers to instant-runoff voting (IRV) or single transferable vote (STV), the main difference being whether only one winner or multiple winners are elected. At the federal and state level, instant runoff voting is used for congressional and presidential elections in Maine; state, congressional, and presidential general elections in Alaska; and special congressional elections in Hawaii. Since 2025, it is also used for all elections in the District of Columbia.
Single transferable voting, only possible in multi-winner contests, is not currently used in state or congressional elections. It is used to elect city councillors in Portland, Oregon, Cambridge, Mass., and several other cities.[2][3]
As of April 2025, RCV is used for local elections in 47 US cities including Salt Lake City and Seattle.[4] It has also been used by some state political parties in party-run primaries and nominating conventions.[5][6][7] As a contingency in the case of a runoff election, ranked ballots are used by overseas voters in six states.[4]
Since 2020, voters in seven states have rejected ballot initiatives that would have implemented, or allowed legislatures to implement, ranked choice voting. As of June 2025, ranked-choice voting has also been banned in seventeen states.[8][9][10]
Notwithstanding apparent efforts by RCV advocates to implement RCV in all elections, there exists much public, private, and academic hesitation as to the viability of such an undertaking. Complexity, cost, possible promotion of strategic voting, and issues of transparency are among issues cited as barriers to adoption.[11]
