Since 2004, San Francisco has used ranked-choice voting to elect its mayor, board of supervisors, and other officers. Voters rank their choices on one ballot rather than returning for a separate runoff. Here you can see past results and try practice polls.
This year, San Francisco has four ranked-choice contests that could require multiple counting rounds. Supervisor districts 8 and 10 have open seats, as Rafael Mandelman and Shamann Walton are stepping down. In districts 2 and 4, appointed supervisors Stephen Sherrill and Alan Wong seek to retain their seats. The 10 candidates in district 10 will give voters more practice using the maximum number of columns (10) supported by the ballot-counting machines.

Ballot styles: A ballot limited to 3 ranking columns was used from 2004 to 2018. Vote-counting machines were upgraded in 2019 to allow up to 10 choices. The 3-choice limit was the subject of a lawsuit rejected by both district and circuit courts. See this analysis of the impact of a 3-choice limit — it shows that it is wise to use all available ranking columns, and to choose lower-ranked candidates who are more likely to survive to later rounds.
These results are an independent and unofficial interpretation of cast vote records released by the San Francisco Department of Elections. The total number of votes countable in at least the first round of the 41 multi-round elections shown here is 2,815,767. DemoChoice is not affiliated with the Elections Department or any candidate.
The Elections Department separates out all “overvotes” (more than one mark in the same column), whereas DemoChoice treats second- or third-choice overvotes as votes for “none of these.” Ballots with no rankings or first-choice overvotes do not appear in these results.
