Board of Supervisors President and Boston native David Chiu, 40, will toss his hat into mayoral ring today. He plans on making it official at around 11 a.m.-ish. Chiu, if you recall, caused minor waves within elite wonk circles after helping Ed Lee land the interim mayor gig.

"Chiu has been considering the move since at least the start of this year, when he played kingmaker as the swing vote to name Ed Lee as interim mayor, parting from his progressive colleagues to do so," reports SFBG. "With no strong progressive candidate yet in the mayor’s race, the question now is whether Chiu will try to win over the left and if he can be successful in doing so after making several more moderate moves in recent years."

Chiu joins a gaggle of other candidates (e.g., Dennis Herrera, Leeland Yee, Tony Hall, Phil Ting, Bevan Dufty) who seek the esteemed title come November. He represents District 3, which includes Chinatown, North Beach, the Financial District, and Fisherman's Wharf. Before his current Board of Supervisors stint, Chiu was a founder and COO of Grassroots Enterprise, "an online communications technology company."
