He's not even in the race officially, but former Sen. Fred Thompson is scoring well in California's presidential sweepstakes. His poll numbers there lag behind only Rudy Giuliani's, several state legislators are raring to help when he gives the green light, and let's face it: California likes actors turned politicians (Think: Ronald Reagan and Arnold Schwarzennegger). But campaign insiders are downplaying Thompson's (aka Arthur Branch from Law & Order) celebrity fundraising draw. "Hollywood is still Hollywood. They tend to mostly be on the left," says pal Ken Khachigian. "While there will be a lot of personal friends, I don't see it as a bonanza or a mother lode for this campaign."
