The truth of the matter is, nobody knows what is going to happen next. I seriously doubt the morale of our troops will deflate overnight or that the Dems will start impeachment.
I've heard rumors that range from several/varied investigations to Cheney leaving and McCain taking his place to position him for 08.
The truth of the thing is: nobody knows.
no way, no potential 2008 candidate wants to be associated that closely with the administration going into 2008.
