Romney Holds Small Lead in Arizona

A new Public Policy Polling survey in Arizona finds Mitt Romney leading Rick Santorum, 36% to 33%, followed by Newt Gingrich at 16% and Ron Paul at 9%.

Key finding: “One thing to keep an eye on over the next week is whether Newt Gingrich can hold his support. 16% is pretty good for him compared to what we’re finding other places right now, but only 46% of his voters say they’re solidly committed to him. 40% of his supporters say that Santorum is their second choice, compared to only 25% for Romney. If Gingrich’s supporters see he’s not viable and decide to jump ship the race could get even closer.”
