South Carolina exit polls follow-up

Lots of news coming out of the South Carolina Democratic Party. If the surprise news from Nevada was Obama's endorsements not translating into voters - it looks like the story in (the other) SC was Obama's ability to build a much stronger voter block. Lots of folks are now reviewing the exit polls to try to explain how the scope of this magntiude was missed. A couple of good reads are David Paul Kuhn of Politico.com and Mark Blumenthal at Pollster.com.
