Romney Ad Hits Huckabee — Again

Latest salvo airing in Iowa echoes familiar attacks on spending, immigration, clemency-- plus Rice's foreign policy put-down. Watch ad above.   Second negative ad of the day from Romney.   Plus: Huckabee concerned about Romney attacks but has no plans to strike back in paid media -- doesn't know for sure if he is doing the right thing. "We'll find out next Thursday."   Update: NY Times says the ad "contains some misleading information."   Brody Files: "Fair or not, perceived or otherwise, Romney has developed the reputation as someone who will change positions or just say anything to get elected President."
