Showing Hillary Clinton with a two-point lead? The Obama campaign is very skeptical, but, for what it's worth, so is the Clinton campaign. Mason-Dixon's latest numbers -- Obama has a seven point lead -- are seen as more of an accurate snapshot of where that race is.
AN OBVIOUS question about the Insider Advantage numbers is that Obama receives only 65% of the black vote in the sample; also, blacks tend to make up about 40% of the SC electorate - they're 37% of the early voters -- and yet they're 25% of the electorate in the IA poll.
