Unfortunately, McCain will have to make do with Arnold riding shotgun on the trail. Yesterday on the plane ride to California, the senator broke the news to reporters that Stallone won’t be stumping for him anytime soon. After hearing of his surprise endorsement, McCain tried calling Stallone, but reached his wife instead, who told him that Rocky was in Europe promoting his new Rambo film. “I was very disappointed,” McCain said.

But not to worry. There’s another familiar Hollywood face lending his support to the Straight Talker’s campaign: Wilford Brimley. You probably know the walrus-mustachioed actor as the kindly old grandpa in the Quaker Oats commercials. But the guy’s got some action movie cred of his own, including playing the evil mob enforcer who tried to off Tom Cruise in “The Firm.” Brimley has endorsed McCain, too, and has been showing up randomly at campaign events in recent weeks. The latest Brimley sighting was on Tuesday night, when McCain ran into the actor at the rally celebrating his Florida primary win. “I’m glad you’re here,” McCain told him. Brimley, the senator said, grabbed his hand in a firm shake and gave him an intense look. “Do or die,” Brimley counseled in his gravelly baritone. “Do…or…die.” It’s enough to send chills down your spine…and make you glad Arnold’s somewhere close by.
