Let’s be blunt: Michael Moore is one ungrateful leftist hack. CNN had showered him with three hours and ten minutes of face time (repeats included) on "Larry King Live" and "The Situation Room," helping him sell his latest socialist film "Sicko." That kind of attention would make a conservative drool. But when CNN aired a "fact check" piece on his documentary, adding a fraction of balance, he declared jihad, promising in a letter to be CNN’s "worst nightmare."
