On another thread with George, I believe we're down to whether the Supreme Court has the power to interpret the Constitution. But the question of whether such delegation has been done in the past by Congress and has been upheld by the Supreme Court is over.
First off I disagree with this statement...and perhaps this is the crux of the arguement.
I read your previous posts...and I see that you have not come down either way on Fast Track.
For simplicity's sake, I'll just say that I feel that Fast Track sidesteps the Constitutional requirement of advise and consent by disallowing the submission of ammendments.
