You misunderstand what he said, as did I until I listened to the followup. He means it was the greatest political achievement DURING his lifetime, not that he had anything to do with it.
Besides Slick Willy, just how many successful elections has Carville been a part of?
I can't think of any...
You can't count the Israeli election where he helped Barak because that's well...in Israel.
What is my point? My point is in the corporate world, He'd be out on his ass because as a consultant Carville is pretty much a bust.
I know that Carville's contribution to the Bush landslide victory was not intentional and that he was not aware of the meaning of his words.
