Bush admits it right to their faces because he's been rankly lying about anything and everything ever since he ran for president and never, not once, paid a penalty for it. Think about it carefully--for anyone else a public admission of lying would be absolutely devastating on a professional and personal level.
Sorry, dear, I lied about sleeping with that perky admin half your age. No big, right? Yeah, boss, I said I delivered all those parts when I actually drank beer for two hours. So?
But for George Bush implacable rules of life just vanish, so he doesn't care, admit it right out loud on the record, why not? This horrifying national psychosis--words chosen with great attention--was very carefully and deliberately enabled by The Washington Post as they scrubbed their stories to hide the lying.
Now, it's a Bad Thing to lie to the American People and to Congress. Particularly to members of Congress who's campaigns were damaged with all the "stay the course" rhetoric and public defense of Rummy right up to the "Heave Ho" moment.
But, hey, such trivial considerations of consequence are beneath our "decider." I can't complain about the outcome, of course. I merely point out that trusting a known and famous liar ain't the path of prudence, as many Republicans found to their cost this past election.
And meanwhile, the WaPo is trying to revise history - unaware of the Google Cache and The Memory Hole, apparently. These days, revising web history is merely an amusing spectacle of futility, rather like a cat covering up on linoleum.
