Keith Olbermann -- GOP Fear Ad

Keith issued arguably his most powerful Special Comment yet tonight. This time he takes on the GOP's newest fearmongering ad which quotes Osama bin Laden and Ayman al-Zawahiri superimposed over pictures of explosions with the sound of a ticking bomb in the background. As if that wasn't enough, it's topped off with the cryptic message echoing LBJ's 1960 "Daisy" ad that ran just once: These are the stakes.
