I think they would make a kick-ass twosome
A woman President and a black Vice President. They are the two most powerful Democratic candidates and they would serve as new models for the American people. We need a change.
I think both are passionate about change that if they ever decided to join forces, it would be a boon to American politics because I don't see either of them rolling over that easy, for anyone.
(Except Hillary, who would roll over for Bush and Cheney, and plans to do so).
