Romney seems to be consistently topping out at 25%ish, in a three way race between Romney, Newt and Cain 25% is not going to win. So the numbers do not support the assertion (pushing Newt).
I have been reading various versions of the "Newt is running interference for Romney" more then I like. Never is one ounce of proof provided. It would be great if you could provide some documentation to support the claim. Thx.
Any poll where they use actual GOP voters you get Cain or Gingrich at the top and Romney at the back. When they include massive amounts of independents you get Romney catching up. So any poll you see Romney in the lead you know has way more independents than GOP voters.
