Kat Anderson, a labor attorney; Schuyler Hudak, a startup founder; and Nick Josefowitz, the San Francisco BART Board Director, are candidates.[3] Former Supervisor Michela Alioto-Pier was considered a potential candidate,[4] but a ballot proposition on the June 2018 ballot limiting Supervisors to two terms in their lifetime, rather than the present two consecutive term limit, prevented Alioto-Pier from running for a third term.[5]
