Imagine a disheartened Democrat Convention, Romney has a double digit lead in internal polls, the economy in in the toilette (still) and Iran is about to test a Nuke. It is time to announce a VP and the "Draft Hillary" chant begins, do you think she she wouldn't accept, for the good of the party? Bill would drug her with roofies and prop her up at the podium like a ventriloquist's dummy to accept the VP nomination.
This election could boil down to which party dislikes their candidate the least.
