Instant Runoff Voting (IRV) is a type of voting method in single-winner elections where voters rank candidates and one winner is chosen. IRV is commonly referred to as “ranked-choice voting” in the United States (though this can be slightly misleading since there are other forms of ranked voting), “preferential voting” in Australia, and “alternative vote” in the United Kingdom. While these names are used interchangeably and inconsistently, all refer to elections where voters rank candidates.

Voting uses technologies that range from hand-counted paper ballots to electronic voting machines resembling bank ATMs. Until the disputed 2000 presidential election, most voters didn't give a second thought to how they cast their ballots, but since then, voting technology has become much more controversial.
