A little Scripture is appropo:
"Therefore, let him who thinks he stands, take heed, lest he fall."
Of course in this case, we want them to fall, so let them keep thinking they've got it in the bag.
It wouldn't be the first time Bush was misunderestimated.
I'm worried, but history has shown W usually saves a trump card or two when needed. He has laid pretty low while getting absolutely creamed so far this year. I have to believe he is going to open up a can soon.
