Romney Holds on to Small Lead in Arizona

Willard Romney holds a 3 point lead over Rick Santorum in Arizona 36 to 33 percent. Gingrich is third with 16 percent while Ron Paul gets 9 percent. Predictable to everyone but establishment Republicans John McCain's endorsement isn't doing Romney a whole lot of good in Arizona. Only 15 percent of voters say they're more likely to vote for a McCain endorsed candidate, compared to 30 percent who consider it a negative, and 53 percent who say it doesn't make a difference either way.
