Is the Bottom Falling Out for Fred?

    My colleague David Bernstein has the news on the latest GOP poll in South Carolina, which shows Mitt Romney surging. The equally significant news from the poll (if, of course, it's accurate) is that Thompson appears to be sinking in a state he has to win -- given that he already looks like a goner in both New Hampshire and Iowa.
    If this poll can be believed, his campaign now appears to be in significant trouble. A major ad buy would seem to be in order.
