Ranked choice voting (sometimes referred to as Instant Runoff Voting) is a method of voting where instead of voting for a single candidate, the voter ranks candidates on the ballot in order of preference – first, second, third, and so on. Voters can cast their vote for the candidate they truly prefer knowing that if their first choice can't win, their vote instantly counts toward their backup choice. This simple voting method gives voters more choice by eliminating the fear of throwing away your vote on someone who can't win. It also avoids the problem of similar candidates splitting the vote and enabling someone to win who a majority of voters does not support.
Ranked choice voting is a nonpartisan change in voting logistics that sometimes helps Republicans and sometimes helps Democrats and always makes government more representative.
