Smart Politics reports high number of Huntsman attacks on Romney during debates.
The Huntsman campaign has deployed websites, online videos, and snarky statements and tweets in a wide-ranging effort to drag down Romney's New Hampshire poll numbers. During the seven debates in the fall, Huntsman attacked Romney twelve times, more than he hit any other contender, according to analysis done by the University of Minnesota's Smart Politics.
