I felt embarassed for Bush. I made the same comment about the job interview question to my wife while we were watching it.
I don't know if the questions were given to him beforehand, but even if they weren't, I would assume his advisors and him would try to anticipate what questions would be asked, and have a practice session to ensure a smooth delivery. None of the questions seemed to be unanticipatable, if that's a word.
Bush was all over the place. Very embarassing to watch. He even had some long pauses when he lost his train of thought. Not good.
I got the impression there were some things he wanted to say, but was stopping himself. Along the lines of "COME ON! Who could have foreseen a bunch of guys with box cutters hijacking four airplanes at the same time and crashing into the WTC and Pentagon!!! GIVE ME A BREAK!!!"
He started on the right track when he said that the American people wouldn't have supported a pre-emptive attack on Afghanistan because of a vague threat prior to 9/11, and afterwards he felt Iraq was a greater threat and acted on it and he is in trouble with some people for that.
I made the exact same point a few weeks ago.
It was amazing the number of reporters who kept trying to get him to admit he was wrong. Like that's going to happen when the whole world, including the terrorists, are watching. He is to be commended for not buckling, and for his steadfastness in his committment to Iraq. He will not walk away and leave them hanging.
