|Ranked-Choice Voting in San Francisco||
Since 2004, San Francisco has used an instant runoff process to elect its mayor, board of supervisors, and other officers. This way, voters rank their choices on one ballot, rather than vote for one candidate in one election and then another in a separate runoff election. Here, you can see past results and try a Ranked Choice practice poll.
Rank the candidates you support, in order of preference.
Your vote counts for Bob, your first choice. Nobody has a majority mandate from voters.
Kim gets enough of Bob's second choices to get a majority.
In this count, because Bob was eliminated, your vote counted for Kim, your second choice.
November 2020 election
The November 2020 election had open seats in districts 1 and 7, each with 7 candidates. These contests were the first to see the benefits of the new voting equipment and ballot style that allow all candidates to be ranked. Preliminary results show a large amount of vote splitting in the first round of these contests. In district 7, the first-round leader had less than 25% of the vote, and another candidate accumulated a majority after several rounds of elimination. Results will be posted here after the city completes its count. Try voting in practice polls here to learn about the candidates and how ranked-choice voting works.

This page shows results of multi-round ranked-choice elections in San Francisco since 2004.
The total number of votes countable in at least the first
round of the 28 multi-round elections shown here from 2004 to 2019 is 1,851,043.
The results released by the Elections Department separate out all "overvotes" (more than one vote in the same column), whereas the DemoChoice
software treats second- or third-choice overvotes as votes for "none of these". Ballots with no rankings or with first-choice overvotes do not appear
in the DemoChoice results.
For the elections with new voting machines starting in 2019, invalid write-ins were removed before overvotes were removed. The Elections Department said that they removed these in the opposite order.
Performing the count either way with the released ballot data gives results close to, but not exactly equal to, the official results.
** indicates contests where the winner overcame the leading first-round candidate in later rounds.
* indicates contests where a candidate who was not one of the top two in the first round was in the top two in the final round.

Ballot styles: A ballot limited to 3 choices 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 that was rejected by both the district court and, on appeal, the circuit court. Here is an analysis of the impact of a 3-choice limit. If such a limit is imposed, it shows that it is wise to use all 3 choices, and choose lower choices that are more likely to win.
