One moment that Cheney really just laid into Edwards was his pointing out Ewards Senate attendence records.
He said something like:
"you have missed 73 percent of intelligence meetings, you have one of the worst attandence records of anyone and have missed a lot of key votes. People in your home town newspaper refer to you as Senator gone.
I, as VP am President of the Senate. I am there almost every Tuesday when they are in session and the first time I have met you is when you walked on stage here tonight."
Good debate. Cheney won.
