Perry's drop in the polls in SC has been dramatic since a high of 36 percent in August. (now at 5 percent)
However, with all these media inflated surges it seems that anything is possible (though Perry may be a tough sell if the reason he went from 35 percent to 5 percent in four to five months are his various snafoos.) Perry may be unvetted, but if most SC voters think he is an idiot, it may not matter.
Also note, how Frothy's finish in Iowa suddenly surged him in the SC polls. Does Ron Paul's second place finish in NH do the same for him in SC? I think it will boost Ron Paul at least a few percent from increased interest.
