There is a straightforward and elegant solution: ranked-choice voting, also known as instant-runoff voting. Already in use all over the world and in cities and towns across the United States, it’s a popular and proven way of electing leaders who are — what a radical notion! — actually supported by most voters. It is effective in any multicandidate race, but it’s ideal for making sense of a large and fractured pool of candidates.
Ranked-choice voting works on a simple premise: Instead of being forced to choose a single candidate, voters rank some or all of the candidates in order of preference — they rank their favorite candidate first, their next-favorite candidate second, and so on. If one candidate wins a majority of the vote outright, he or she is the winner. If not, the ballots are tallied in a series of rounds. In each round, the candidate with the fewest first-place votes is eliminated. Each ballot ranking that candidate first is then transferred to the candidate whom it ranked second. The process repeats, eliminating the lowest-scoring candidate and redistributing his or her ballots, until one candidate has more than 50 percent of the vote.
