I wonder why the "commission" didn't do a bit of research before they Lewinskied Clarke in the first place? I am sure they have everything Condi ever uttered in public all lined up and ready to go for tomorrow.
It is my understanding that Clarke had already given several hours of private testimony, which were not consistent with his public testimony. In my opinion, the Rats on the committee (who all conveniently had his book) knew that he was going to slam Bush in his public testimony.
In addition, I believe that the book was altered after it was sent to the White House. Apparently (and I have not read it) the introduction and the last chapter are the ones which attack Bush. Everything else is pretty much neutral. I think he added those two portions on after the book was vetted.
I am dead certain they are going to try and ambush Condi tomorrow. I also assume that the White House knows this, and they are ready for it.
