Will it be Tom Torlakson or Mark DeSaulnier? Those two have to be the frontrunners in the race to take the seat of outgoing East Bay Congresswoman Ellen Tauscher. Yesterday, Tauscher accepted a post as the State Department’s lead arms-control negotiator. Torlakson, a former state senator and current Assembly member who has huge name recognition in Tauscher’s mostly Contra Costa County district, will be a force to be reckoned with. But DeSaulnier is no slouch. He raked in 70 percent of the vote in last year’s Democratic primary, and 67 percent in the general election.
