SAN FRANCISCO – After nine months of headlines and bitter legal squabbling, Sheriff Ross Mirkarimi's fight for his job could reach a conclusion Tuesday as the San Francisco Board of Supervisors is set to vote on whether to remove him from office over a domestic violence case involving his actress wife.

It would take at least nine votes from the 11-member board to oust Mirkarimi, who was elected last fall and mired in controversy before his swearing-in ceremony. Five board members currently are campaigning to keep their jobs.

"I wouldn't be surprised if it ends up 7-to-4 to keep him or 11-0 to remove him," University of San Francisco political scientist Corey Cook said Monday. "We don't know what to expect. It's been such a roller coaster that I can't even venture a guess."
