Rasmussen: McCain by five in Arizona

Three polls have come out in the last three days that show Arizona is probably tighter than makes John McCain comfortable. Rasmussen today released a poll that shows Obama is down by just five points in the Grand Canyon State:

Obama 51
Obama 46

Previously, the smallest lead Rasmussen found was a nine point spread in June with McCain favored in his home state, 49-40. Myers/Grove this weekend published results that showed McCain four points up; similarly, Zimmerman & Assocates showed McCain only two points up.
