I think there is quite a bit of difference between a Rep, representing his district, and the job of leading the free world! To begin with, Bush was privy to info not shared with the public. We may never know why and how he made decisions we did not agree with, but a Rep listens to his people and is supposed to forward their opinions into congress.
That's their frikkin' JOB! Not forwarding his/her idea of what the country should be in their opinion! Not their choice! It's the people's choice!
I understand your views, I really do - or I think, I just hold a different view.
