CNN poll shows 55% pick Ryan to win, 39% pick Biden to win.
Ryan will look young yet sound experienced, vigorous, attractive, and sound knowledgeable and in control of the facts. A fresh face.
Ryan wins.
I read some where that Young women are often late deciders. I think Paul Ryan can win a few % of under-35 women voters if he shows of his awesome abs! But I think Edwards proved you need more than a pretty face and that Paul needs to sound smart and calm.
Don't forget about Biden's Scranton Cannons:
