Arizona is a state that is becoming much less reliably Republican, along with a few others in the west. The Democrats have a realistic shot at it in '08, along with New Mexico (which of course they have won recently), Colorado, Nevada, and perhaps Montana.
Yeah, take Montana out and I'll agree with it. Montana is not going to trend in Presidential elections anytime soon. The only reason Montana went Democrat in 1992 was because Bush was never that popular in the state, and Perot dropped the percentages.
