I bet I know the Iowa Caucus nominating electorate a bit better than you do. The poll you cite is meaningless.
Since Reagan, every delegate that has come out of Iowa has pledged to support only pro-life nominees, and the continuation of the Reagan platform.
That could, theoretically, save McCain, but your boy is going to get spanked hard.
If he doesn't, there is no hope for the GOP anyhow. A total abandonment of its core principles will spell its electoral doom.
If Carville isn't paying you and your ilk, he should be.
Opinion polls now are totally meaningless. You're setting yourself up for a real let-down when polls a week or so from the Iowa caucus comes out and then they actually take place.
I hate this Iowa/NH decides it thing. It just raises my blood pressure every four years to see this same idiocy played out.
