Nearly everyone "won" during the Iowa Caucus debates last night. However, if I had to give my top three picks, I'd say that Rommey, Cain, and especially Newt Gringrich came out on top.
Gringrich was an especial surprise given the "fight the press" offensive style he took, and clearly established himself as the one not only with the most ideas, but the specifics on how to pass his ideas. It was almost "Chris Cristici-ish" how he conducted himself in that debate: as a fighter with the know-how and no-prisoners attitude to get things done.
Rommey and Cain lived up to expectations, coming off as the most presidential with their clear messaging and allusions to executive experience. Rommey's compliments to Cain himself as a fellow executive also elevated both. Nonetheless, I opine that Cain could have gone even further had the debate shifted in a manner that would have enabled him to relate his background specifically to the questioning.
Overall, it was a night of excellent ideas that sharply contrast to the failed presidential administration we deal with now. If one candidate elevated himself the most however, I would give it to the conviction of Gringrich.
