Wasting time in PA.
Having volunteered in PA, the loss by ELEVEN points tells me that McCain's biggest mistake may well have been that his internal pollsters were morons. We were told that not only PA, but a number of other races in other states were highly competitive and the public polls were mistaken. WRONG. As bad as even, say, Gallup was in PA, he was within the margin of error here. McCain's internals weren't even within twice margin of the final result.
