When it comes to Julian Castro's mayoral ambitions, the question hasn't been "if" but "when," as in "When will he make it official?"
The former councilman, who lost a hotly contested mayoral contest to Phil Hardberger in 2005, looks to be a clear front-runner in next year's race to succeed Hardberger. He'll officially declare his candidacy on Sunday, December 7, at San Pedro Park (1315 San Pedro) at 1:30 p.m. Castro announced the event by sending out invitations to 390 Facebook friends, and so far 47 of his pals have confirmed that they'll be there. But don't look for Diane Cibrian in the front row.
