Bob Filner left Congress to win election last November as San Diego's first Democratic Mayor in 20 years. In Washington, the New York Times says he was known as "notoriously brash and cantankerous." Now, he's in a fight for his political life with one former supporter calling him, "tragically unsafe for any women to approach" and another saying, "he does not deserve to be mayor of this city any longer." Filner's apologized, but he's refused to quit. Steve Erie teaches political science at UC San Diego, where he's director of the Urban Studies Program.
