Each voter may rank the different choices in any order. Votes are initially counted for each voter's number one choice. If a candidate has more than half of the vote based on number one choices, that choice wins. If not, then the choice with the fewest number one votes is eliminated. Voters who had chosen the defeated choice as number one now have their number two choice counted as number one choice. The process continues over multiple rounds until a choice has more than half the votes.
