As noted by Hugh Hewitt late last week, Dean has hit the trampoline; all the polls now confirm that he's gaining support (or, more accurately, regaining support). This probably hurts Kerry most of all; he does not want to be one of two Northeasterners competing in the South and Midwest. It helps Edwards, as Clark's apparent melt-down means that he will be the only Southerner left standing, especially if he can slip ahead of the general tomorrow.
My prediction is that Kerry wins New Hampshire, Dean comes in second, close enough to claim the comeback kid mantle. Edwards finishes third, Clark finishes out of the money and folds his tent. Joe Lieberman's not going anywhere.
