Reports of Perry's demise are greatly exaggerated, apparently.
This corpse is still warm.
Anyway, his state polling numbers (especially in the early states) are terrible. Iowa is okay, but the support there is quite shaky and he hasn't campaigned there much. In New Hampshire he's barely even a frontrunner, he's now losing Florida, and South Carolina could very well be stolen if the "frontrunner" label is gone due to losses in Iowa and New Hampshire (in particular, if a candidate other than Perry or Romney gets Iowa, Perry loses all real appeal)
