of course. i think that may be a backup plan. if he's losing in the final weeks. have biden back out for personal reasons, and put clinton on the ticket as VP.
think about it. the far-right wouldn't have time to bash hilary in the press for all her luggage and bill's connections and issues. Instead, it'd be "Hi shallow idiot women voters who only select a candidate based on sex organs - I came to my senses"
And a lot of Palin voters would jump right to his bandwagon. It's entirely possible.
*oooh i just noticed Intrade.com has a 7.6% chance of Biden being pulled from ticket
Looks like others are thinking this way also...
