This would tighten to 30-26 for Mitt/Newt if Perry dropped out before Saturday.
Perry hasn’t enough numbers in any poll to make a difference by dropping out. Nor could he credibly endorse Newt, after that pointed remark he made about Newt’s character (”If you’d cheat...”)
It’s Santorum who’s being dog in the manger right now. The numbers he’s polling will do him no good, but he won’t let anyone else have them.
