No, that’s not what it means. This was not a poll of FR Newt supporters, it was a poll of the general population of Newt supporters.
And yes, intelligence, accomplishment, resume are more important than ideology for many voters and those folks would, out of this entire field, normally pick Newt first and probably Romney second. They would have also been perhaps enamored of Cain (business) or Perry (governor).
They would not have had any interest in Santorum or Paul or Bachmann or Huntsman.
Again, this is about the “non FR” universe, which some here, sadly, fail to remember does exist.
What are Romney’s accomplishments? What tells you he is intelligent? I haven’t seen it. In the words of Alan Jackson, “...it’ll just take money.” and his was inherited, or from daddy’s rich friends. He does what Carl Icahn did except Carl risked his own cash.
