Jeb Bush: 55-60%
Marco Rubio: 10-20%
Rand Paul: 10-20%
Donald Trump: 5-10%
Mike Huckabee: 3-5%
Scott Walker: 3-5%
John Kasich: 3-5%
Bobby Jindal: 1-3%
Lindsey Graham: 1-2%
Rick Perry: About 1%
Ben Carson: About 1%
Carly Fiorina: About 1%
Ted Cruz: 1% or less
George Pataki: Probably less than 1%
Peter King: Less than 1%
Rick Santorum: Less than 1%
Everyone else: Less than 1%
Chris Christie: Have a feeling he won't run, but if he does, I would say between 5-25% because of his unique personality (which might overcome his myriad of closeted skeletons)
I love the way you went about that. I mostly agree and want to emphasize Christie's wide range. IF someone were to tell me that one of the three guys that title this thread were not the nominee next summer, I'd say, "Then it must be Christie."
My disagreements:
Walker higher: 10-25%
Trump, Huckabee, Jindal, and Graham all down with the "about 1% crowd"
Carson with Kasich at 3-5%
