What is Ranked-Choice Voting?
Under ranked-choice voting, San Francisco voters can rank their top three choices for a single office.
If no candidate wins a majority (over 50%) of first-choice selections, last place candidates are then eliminated and voter’s second and third place choices are then redistributed until a candidate wins a majority. This makes it possible to elect local officials by majority vote without the need for a separate run-off election.
San Francisco voters passed Ranked-Choice voting as an amendment to the City Charter in March of 2002.
