From SFGate: San Francisco Supervisor Jane Kim signaled her intent to enter the 2018 mayoral race Wednesday, requesting nomination papers from the city’s Department of Elections.
Kim, a stalwart progressive as a supervisor, has long been rumored to be considering a bid for the mayor's office. She was first elected to the Board of Supervisors in 2010.
She and any other candidates eyeing a run for mayor have until Jan. 9 to file the necessary paperwork. Though any number of people may take out the papers to run, none of them are official candidates until those nomination papers are returned.
