Extrapolating from the returns so far suggests that the turnout in South Carolina is up something on the order of 30% from 2008, when it was 445,677. That may turn out not to be the case if the returns so far are from the heavy-voting precincts and so the extrapolation may be unduly high. But if turnout really is up, that is a big contrast from Iowa, where turnout was 3% over 2008 and New Hampshire, where it was up 4%.
