More or less, the same thing happened with Occupy. Its more that SF is a major hub of rebellious anarchists who are utterly inept at running political campaigns or creating anything useful.
Occupy kind-of sorta had meaning, until those west-coast anarchists started storming banks, breaking windows, and turned the whole event into a "F* the Police" festival.
That sort of behavior scares away the Teachers Unions, the Police Unions... and the many others (who are part of the 99%), and greatly hampers the movement. Nevertheless, you can be sure that the non-assholes are hoping for a solution.
