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.
She bills herself as an "anti-politician," counting on grass-roots support and endorsements from labor groups. The 250-member Sonoma County Deputy Sheriff's Association has yet to pick a candidate in the race, but its president, T.J. Van Bebber Jr., was at Wednesday's event.
He said a decision on an endorsement could come in two or three months.
"We want to get out and listen to what's being said," he said.
Shanahan didn't get into specific criticisms of Ravitch, saying she merely wanted to announce her candidacy. But she promised an "issues-based campaign" to include future public forums or debates.
Political watchers said Ravitch isn't particularly vulnerable. She's respected as a top trial lawyer and has had no major public relations disasters.
However, detractors said she's not necessarily a good manager. Some have accused her of cronyism for hiring political supporters and for excessive turnover at her Family Justice Center, which has had three leaders in less than two years. Others said she lacks transparency and is more concerned about reelection than running an office with 110 employees and a more than $20 million budget.
Most recently, her office has come under fire by crime victims who said they weren't consulted on plea bargains.
Ravitch said in a written statement she's proud of her record and looks forward to "a spirited and civil debate."
