Salon columnist Sidney Blumenthal offers a watch-an-ad-to-read-it-all screed entitled "From Gulf to shining Gulf". He thinks Bush is stuck in a "feedback loop". Whatever the merits of his screed which I didn't read, he does point out the following interesting fact:
Speaking about Iraq, Bush said the following on 2/4/04:
"We will do what it takes. We will not leave until the job is done."
Speaking about Katrina, Bush said the following on 9/15/05:
"We will do what it takes. We will stay as long as it takes."
Maybe he's thinking so fast how to do good for America that he put the politician part of his brain on auto-pilot. Or, maybe the tiny speaker connecting him to Karl Rove failed and he fell back on something he had already said.
