Democrats who really don't want Biden, Clinton or Cuomo to be the nominee.

If Arne Duncan didn't have such a weird lisp in his voice, he would be a good candidate.

Nobody mentioned outside of Biden or Clinton feels like a winner at this point.  Look, sound, and act are the three keys to a good candidate.  All of the rest miss the mark in some way.  

Cuomo has the look and the sound, but it is not clear that he is in line with the Democratic platform--he's basically the Democratic Mitt Romney.  He'll get attacked from the left in the primaries and there's little hope he can recover his image to win.  

O'Malley has the look and the act, but sounds like a boring dork.

I cannot picture Schweitzer or Hickenlooper as a President of the United States.

Michael Bennet? Maybe.

Cory Booker surging to the national forefront and staying there is probably the Democrats best chance at a "new face" winning, but I don't think he's ready.  Kirsten Gillibrand is also interesting.  So are Kamala Harris and Julian Castro, but both are 2020/24 material more than 2016.
