San Francisco has a new mayor.

Yesterday afternoon, former state senator Mark Leno conceded the June 5 special election to London Breed, president of the Board of Supervisors.

Leno concedes, Breed thanks supporters

Breed, 43, will be the second woman to manage the city and county of San Francisco and the first woman of color to run one of the nation's largest cities.

After Leno conceded in a press conference at his SoMa sign shop, Breed thanked supporters on the steps of City Hall.

"The message that this sends to the next generation of young people growing up in this city is that no matter where you come from, no matter what you decide to do in life, you can do anything you want to do," she said. "Never let your circumstances determine your outcome in life.”

Election results will be officially certified on July 10, whereafter, Breed will begin her term, which ends in January 2020. After she takes office, she's expected to appoint someone to fill her vacant District 5 seat. 

Mandelman elected District 8 Supervisor

In District 8, City College Trustee Rafael Mandelman has defeated incumbent Supervisor Jeff Sheehy, who was appointed by late Mayor Ed Lee. Sheehy filled a vacancy left by former Supervisor Scott Wiener, who was elected to the state Senate in 2016.

In November, District 8 voters will decide between Mandelman and Lawrence "Stark" Dagasse to determine who will serve a full four-year term in the seat; Sheehy has announced that he will not seek reelection.

Tang declines to seek reelection

Yesterday afternoon, District 4 Supervisor Katy Tang announced that she will not seek reelection this November.  

"It is time for me to pursue a change in my life and new challenges," Tang wrote in a letter to her constituents. "I do not yet know my next steps, but I do know that personal growth is something that I value and am seeking."

Jessica Ho, one of Tang's legislative aides, announced her candidacy for District 4 Supervisor yesterday at Uncle Benny's Donut and Bagel shop on Irving Street in the Outer Sunset.

Ho joins declared candidates Adam Kim, Mike Murphy, Jimmy La, Miao Li Lovett and Gordon Mar.

“It’s an honor to serve district residents every day, and I am looking forward to continuing the important dialogue around keeping our neighborhoods clean and safe in this election season and beyond,” said Ho. “I am committed to improving quality of life for all residents, creating housing that is affordable, and reducing homelessness by addressing its root causes.”

Ho has already earned support from Assessor-Recorder Carmen Chu, Mayor Elect London Breed and the Edwin M. Lee Asian Pacific American Democratic Club.
