Ranked Choice Voting is the familiar runoff process done in a single election. In St. Paul it is used in elections for St. Paul City Council and Mayor.
The first step is that all ballots are tallied according to first-place choices. If one candidate wins a majority (50% + 1) among all of these first-place votes, that candidate is the winner.
If not, the candidate with the fewest first-place votes is eliminated and the ballots for this candidate are redistributed among the remaining candidates according to the second choices on those ballots. The process continues until one candidate has picked up a majority of votes.
In the absence of a tie, the system guarantees a majority winner when the field is narrowed to two candidates. If it reaches this point the candidate with more votes than the other will have a majority of the vote.
