The most interesting thing about that poll, is that the non-candidate and flawed and shop worn Newt is sucking up the "conservative" oxygen, because none of the others are getting any traction, as yet, and Mitt has not yet broken the glass ceiling, and may not, given some recent Internet dumps about his willingness to trim to the expedient, and without much creditability, sell it as principle.
Unlike you, I think Mitt has his pluses, but one can't ignore what comes out of his own mouth, as one is apprised of same, and trying to make a silk purse out of a sow's ear with such words, is beyond my pay grade, assuming Mitt was paying me, which he is not.
