Under Ranked Choice, each voter selects up to three candidates on the ballot and notes their order of preference. When the votes are first counted, only the first choice is noted. If no candidate wins more than 50% of the vote, then the lowest vote-getter is eliminated. For the next round of tabulation, anyone who voted for the eliminated candidate has their second choice counted. This process is repeated until one candidate wins a majority of the votes.
