In other words, Huckabee can win, Romney might be able to, Palin can’t, and Trump would struggle (but if anyone can overcome negatives, it’s Trump). The others fall somewhere in the middle.
I think that's true. If I'm Bachmann, Pawlenty, Barbour, Daniels or even Santorum, while I'm not happy with where I am, at least I'm comforted with the fact no one knows who I am also. At least there's MUCH room for improvement.
If I have high disapprovals and 80+% of the country knows who I am already, I know I'm toast.
