With 481,991 registered voters in San Francisco, the final effective turnout was an above average 52.61 percent. And while we had projected London Breed would win the mayoral race by a margin of around 2,100 votes, or 0.83 percent of all ranked choice ballots cast, when we first declared her victory, the final margin was actually 2,546 (1.00 percent).
The final accounting for the ranked-choice vote results are outlined in the table above, with London Breed securing 50.55 percent of the final tally versus 49.45 percent for Mark Leno.
Note that 8,219 ballots were “exhausted” (either by having not indicated a second or third choice vote or having already exhausted all three choices) when Angela Alioto was eliminated and another 8,054 ballots were “exhausted” following Jane Kim’s exit. Once again, Breed’s margin of victory was a total of 2,546 votes.
And with respect to the final count of first choice, non-ranked, votes, the top six vote getters were as follows:
1. London Breed 91,918 (36.64% of first choice votes)
2. Mark Leno 61,276 (24.43%)
3. Jane Kim 60,644 (24.17%)
4. Angela Alioto 17,447 (6.95%)
