The headline focuses on Clark gaining, but it seems to me that the race has stabilized some with Dean around 30-32 points and Clark between 23 and 25 points. Also Clark has a higher percentage of voters (25%) to Dean's (17%) who say they might still change their minds. A Kerry win in Iowa probably benefits Kerry at the expense of Clark in NH even more than at the expense of Dean. Makes you wonder who Clark wants to win in Iowa (perhaps Gephardt).
