Instant Runoff Voting (IRV) is a type of voting method in single-winner elections where voters rank candidates and choose one winner.
In IRV, ballots are initially counted for the voter’s highest-ranked choice. A candidate wins if they obtain more than 50% of first-choice votes. If no candidate receives more than half of first-choice votes, the candidate with the fewest votes is eliminated. Voters who ranked the defeated candidate as their top choice then have those votes added to their next choice. This process continues until one candidate receives a majority.
