SAN FRANCISCO — The gap between the two leading candidates for San Francisco mayor shrank to 255 votes on Thursday.
An elections office update shows former state Sen. Mark Leno still leading President of the Board of Supervisors London Breed in a race that remained too close to call.
But he had been ahead by 1,121 votes on Wednesday.
Breed has the most first-place votes of eight candidates, but Leno is ahead because San Francisco uses a ranked-choice system that allows voters to pick their top-three choices in order.
Supervisor Jane Kim and Leno asked supporters to vote for the other as their No. 2 choice on the ballot. She is in third place.
Leno said he expects the vote-leader to fluctuate.
Elections officials said there are 84,000 ballots left to count.
