This is pretty bad even for Olbermann. Among the many, many highlights; 'as dishonest, as insane as any terrorist; the former vice president has today humiliated himself beyond redemption', 'culpable, morally, ethically for 9/11' and 'At best, you are guilty of malfeasance and eternally lasting stupidity. At worst, sir, in the deaths of 9/11, you are negligent.'.
(Olbermann was talking about the speech Cheney gave which is posted at Berman Post: Cheney-Obama Duel.)
