Voters rank the candidates for a given office by preference on their ballots.
If a candidate wins an outright majority of first-preference votes (i.e., 50 percent plus one), he or she will be declared the winner.
If, on the other hand, no candidates win an outright majority of first-preference votes, the candidate with the fewest first-preference votes is eliminated.
All first-preference votes for the failed candidate are eliminated, lifting the second-preference choices indicated on those ballots.
A new tally is conducted to determine whether any candidate has won an outright majority of the adjusted voters.
The process is repeated until a candidate wins a majority of votes cast.
