I'll just break them down into catagories
Definitely wouldn't get it:
Joe Manchin
Andrew Cuomo
Jay Nixon
Pretty unlikely they'd get it:
Jim Webb
Ed Rendell
Steve Bullock
A contender, but not the most likely:
Howard Dean
Antonio Villaraigosa
The most likely ones:
Luis Gutierrez
Martin O'Malley
Tammy Baldwin
Al Franken
I don't think you can dismiss Cuomo that easily. He'd easily be the most well funded in this field, which is a fairly important factor.
Why would Luis Gutierrez be likely?

Random House members tend to be relegated to a side show in primaries, and the early states such as IA/NH/SC aren't exactly booming with Hispanics, which would presumably be his base.
