San Francisco has been using ranked-choice voting since 2004. The idea is to avoid a costly run-off election and to encourage a winner who has broad support. Here's how it works.
As of Tuesday afternoon, London Breed is still leading the mayor's race with 50.42 percent of the vote, and Mark Leno has 49.58 percent. That's a difference of just 1,861 votes.
The San Francisco Department of Elections released the latest results in the race to fill the mayoral seat left empty by the late Ed Lee. London Breed is now 1,601 votes ahead of Mark Leno, maintaining her narrow lead.
It's been five days since Election Day and we still don't know who will be San Francisco's next mayor. But workers at City Hall are making sure every vote is counted in this very tight race.
Board of Supervisors President London Breed is surpassing former state Sen. Mark Leno by 498 votes in San Francisco's mayoral race, according to numbers released this afternoon.
The San Francisco mayor's race is still too close to call. Mark Leno is still leading, edging out London Breed by just 144 votes four days after the election. Ballots are still being counted.
