SC and FL demographics are very different. Using your reasoning one could say that the FL poll is an outlier. An outlier is not determinable until there are other polls published covering the same general time period and same locale.
SC is a lot blacker and more Christian than Florida. One would think that would play in Cain’s favor. My biggest concern about Florida is Rubio endorsing Romney at the last minute. I hope that doesn’t happen, but my gut tells me it will.
The poll doesn’t include leaners. So they are artificially suppressing the Cain numbers. Neat trick.
Yes, their demographics are different, except for the fact that EVERY OTHER Poll has had Cain stronger in SC than FL.
