Hi Cactus Flower,
I think Santorum is a smart man. His problem, IMO is his religion that he tries to enforce on Americans.
If he could leave that at home, he would have a better chance.
Huntsman, probably the brightest in the lot, doesn't have a prayer.
You're correct, Romney has a ceiling of 25%, republicans just don't trust him.
At this point, I just can't figure out which candidate will win.
