1. Note above that this poll claims itself that it is weighted only for age, race, and gender.
a. That means it is not weighted for political party of preference.
2. Note as well that the poll claims for itself that it is for likely voters who are registered in S Carolina. It explains further that it means "likely to vote in the Republican primary."
3. This means that it could ALL be democrats, independents, or 3rd partiers who just happen to want to vote, for whatever reason, in the republican primary. We ALL know that there is no reason for democrats to vote in the democrat primary. Obama is unopposed. It isn't likely that zero republicans are included, but the point is that there was absolutely no effort to ensure any breakdown whatsoever.
Personally, I think this is little different (maybe worse) than the reuters poll that included as many democrats as republicans in their sample.
In this poll we don't have a clue what the breakdown is.
Bump!!
