The Sonoma County District Attorney's Office is once again a hotbed of political dissent.
Deputy prosecutor Victoria Shanahan announced Wednesday night she will challenge her boss, District Attorney Jill Ravitch, in the June election.
The move was reminiscent of Ravitch's own path to elected office that began about eight years ago. She ran unsuccessfully against then-District Attorney Stephan Passalacqua in 2006 before defeating him in 2010.
Now comes Shanahan, an ex-Mendocino County chief deputy prosecutor hired by Passalacqua in 2007, who will face similar long odds in unseating the one-term incumbent. Ravitch has won endorsements from the five-member Board of Supervisors and Sheriff Steve Freitas and is amassing funds in a campaign war chest.
But Shanahan told a gathering of supporters, including senior prosecutors, sheriff's detectives and criminal attorneys, that she felt compelled to give it a shot.
She said Ravitch has been an ineffective leader in her $205,000-a-year job, is unwilling to listen to criticism and must be replaced.
"Sonoma County deserves more than broken promises," she told a crowd of about 100 people at Cellars of Sonoma in downtown Santa Rosa. "It deserves more than failed leadership ... and compromised public safety."
Some backers who voted for Ravitch in 2010 said they, too, were concerned about the direction in which the district attorney was going. Santa Rosa defense attorney Chris Andrian, who attended Shanahan's campaign kickoff, said the fact that senior prosecutors and homicide detectives are complaining gives him pause.
"What they're telling me, I can't just blow off," Andrian said. "These are people I respect. They are the heavy lifters."
Shanahan, 44, a registered Democrat and Cloverdale resident, is married to Sonoma County Sheriff's Deputy Mike Shanahan and has two children.
