The Zogby poll for the 4 states including SC have a wealth of data under the covers. Here is some of it for SC, formattted as best I can for readability.
...note there's no commentary provided. It appears no one wanted to answer the education question during the survey. if there's more data tomorrow, I will post. Edwards has only 1.7% of <HS vote, Dean 11.0% but most would not say.<p>
