San Francisco will use IRV in future years for citywide offices like mayor and district attorney, joining the ranks of Ireland, Australia and London that use IRV to elect their highest offices. IRV simulates a series of runoff elections but finishes the job in a single election.
Voters rank candidates for each race in order of choice: first, second, third. If your first choice gets eliminated from the “instant runoff,” your vote goes to your second-ranked candidate as your backup choice.
The runoff rankings are used to determine which candidate has support from a popular majority, and accomplish this in a single election.
Voters are liberated to vote for the candidates they really like, no more spoiler candidates and “lesser of two evils” dilemmas.Previously San Francisco decided majority winners in a December runoff election.
