Oh I don't know. Let's try...
Clinton 20
Biden 10-15
Cuomo 10-15
Warren 5-10
New or rumored new Secretary of State 5
Schweitzer 5
Warner 5
I agree that Clinton will lead (regardless of how many denials she gives) and that Biden and Cuomo will be #2 and #3. My guess is probably Cuomo slightly ahead of Biden though.
What about Rubio? I don't Romney will be nearly that high. It'll probably be Christie and Rubio competing for the #1 slot, perhaps also competing with whoever the 2012 VP nominee was (though that might be Rubio). If Rubio is the VP nominee, then he'll be #1 for the 2016 market. If not, then probably Christie. Jindal, Huckabee, Ryan, McDonnell, and Palin will all be doing OK as well.
I don't see J. Bush being nearly as high as 10. Why would he be that high? He was never that high in the 2012 market.
