California Lt. Gov. John Garamendi (D), the first Democrat to formally enter the 2010 governor's race, is now expected to announce that he's planning a run for Congress in CA-10, CQ Politics reports.
The seat is now held by Rep. Ellen Tauscher (D-CA), who has been tapped for a job in the Obama Administration state department. A special election will be called if she's confirmed for the post.
