San Francisco’s first Black female mayor, London Breed, has conceded the race for mayor to Levi Strauss heir Daniel Lurie, pledging a smooth transition, the Associated Press reports.

The AP has not yet declared a winner because tens of thousands of ballots have “not yet been counted and added to the ranked choice voting calculations”.

Breed could not overcome deep voter discontent and was trailing Lurie, a philanthropist and anti-poverty nonprofit founder. She faced four big-name challengers, including two San Francisco supervisors and a former interim mayor.

“At the end of the day, this job is bigger than any one person and what matters is that we keep moving this City forward,” AP quoted Breed as saying. She added that she had called Lurie to congratulate him.

According to AP, Breed’s fellow Democratic challengers on the campaign trail repeatedly hammered her administration for doing too little, too late as homeless tent encampments, open-air drug use and brazen retail theft proliferated during her six years in office.
