ARNOLD ENDORSES McCAIN WHILE ARNOLD’S KENNEDY WIFE ENDORSES OBAMA: The rich really are different — they’re all insane! Schwarzenegger endorsed John McCain last week, after Rudy Giuliani dropped out in disgrace, and after Schwarzenegger weakly claimed he wouldn’t endorse anyone. But at a “surprise appearance” (with Oprah) in Los Angeles on Sunday, Arnold’s trophy-Kennedy wife Maria Shriver said she’s endorsing Barack Obama. WTF? Aren’t the various first couples supposed to at least pretend they’re on the same team? [New York Sun/Baltimore Sun]
