I absolutely understand Lee's point about Dennis Miller.
But for me, this wasn't part of any sort of group-think. It was more about feeling betrayed by someone who I had previously admired. It was really a whiplash effect: "Seriously? Dennis Miller is supporting... who?! And what?!" How can a man that smart and that funny defend that president or that war or that Alaskan governor?
When he snapped over to the Bush camp after 9/11, it was a shock, but it also indicated a disturbing reaction to fear. Miller has repeatedly said that 9/11 scared the hell out of him and so he swore allegience to President Bush no matter what -- and he's stuck by that pledge, irrespective of the incompetence and tragedy wrought by the administration.
In a larger sense, though, this is illustrative of a phenomenon we've witnessed among too many Americans: the nationwide knee-jerk reaction to 9/11 enabled an acquiescence to the unconstitutional and dangerous policies of this administration. Miller, by his own choosing, became a very visible example of this phenomenon.
