SAN FRANCISCO — San Francisco’s first Black female mayor, London Breed, conceded the race for mayor to Levi Strauss heir Daniel Lurie on Thursday, pledging a smooth transition as he takes over the job. The Associated Press has not yet declared a winner because tens of thousand of ballots have not yet been counted and added to the ranked choice voting calculations.
