Marc Ambinder gives us six reasons Mitt Romney should be worried about the Iowa caucuses. Support for Romney is less intense than support for Huckabee; so far the Iowa press has gone easy on Huckabee; a large portion of the social right is beginning to determine that a Huckabee victory in Iowa would prove its relevance; Huckabee is "a more compelling, more engaging public personality than Romney" (ouch!); at the moment the expectations game works to Romney's disadvantage ( his eminence would probably disagree with this one); and lastly the clock is working against Romney. All six points are worth considering, though I'm far less certain than Ambinder is that "the race in Iowa ends before Christmas." Last I checked the caucuses remain scheduled for January 3, 2008.
