Supervisor Dean Preston held a commanding lead in the race to retain his District 5 seat on the Board of Supervisors as election night ended Tuesday.
Preston was ahead over his main opponent, former Supervisor Vallie Brown, with more than 51 percent of the first-choice vote, according to the last results of the night released early Wednesday.
Preston has 17,329 first-choice votes, 3,768 votes over his challenger Brown. The contest does not go to ranked-choice voting if a candidate can secure more than 50 percent of the vote.
Reached Wednesday morning, Preston said he had not declared victory but the vote “seems to be decisive.”
Preston appears to have defeated Brown despite an onslaught of outside spending on attack ads over his handling of homelessness.
The race was a rematch between the two candidates.
Brown, the leading moderate, narrowly lost to Preston last November after Mayor London Breed appointed her to the seat.
Preston is a progressive and a member of the Democratic Socialists of America.
Preston and Brown were among four candidates in the race.
Further results are expected to be released Wednesday afternoon.
