The point is that your data is most certainly contradicted by current polling. It may not tell what party people identify with, but it shows a statistical tie. That means, either McCain is drawing overwhelming support from Independents (which would mean they are not in trouble) or that more people are now identifying with Reps (which means they are not in trouble).
EITHER way... McCain is not in trouble as people are identifying WITH HIM in great enough numbers to be in a statistical tie with either Dem.
I know that is a complex thought and that Desh is too partisan to understand it. But you should be able to comprehend that Dung.
