Bingo. Neverthless, Newt is taking some risk in exposing himself to an attack by Huntsman. Huntsman, despite his flaws, is more free market than the flip-flopping Newt and might be able to wound him if he is effective in pointing this out..
Not likely. A libertarian candidate is ALWAYS going to come across as "more free market" than a Conservative one. If I understand this point, you can be sure Gingrich does, and will use it to his advantage.
Off the top of my head: What could be more "free market" than legalizing drugs?
