Some of the Democrats want Hillary to run against Obama in 2012. So it may be that Hiilary will accept an offer to run as VP with the thought she will be the 2016 front runner.

Owing to this possibility there is a lot of talk about Candi Rice as a VP nominee

All in all it appears to be speculation and/or wishful thinking by voters.

Biden been in my sights since his days at Syracuse and it has amazed me that he has gotten as far as he has?????????????????????/
