Romney is feeling the heat– taking a shot at McCain and getting a blast back. McCain throws in big and little issues in a comical list of insults. It may be that the biggest damage done by Huckabee to Romney was not in Iowa but in NH. To fend off Huckabee Romney has had to dwell on his social conservative credentials, spend gobs of time in Iowa and focus 90% of his fire on Huckabee. Meanwhile McCain has been the steady guy, wooing the locals in NH with his townhall performances. After a week more of pounding it’s not at all certain Huckabee will hold on in Iowa but McCain may very well win NH on the strength of his own efforts helped by the Union Leader and other favorable coverage. UPDATE: Fascinating reading here on “apprehension but not panic” in Romney camp.
