How is that the least bit relevant? All of those polls clearly under-estimated McCain since they showed a smaller margin than the actual one on election day. With 56% of the vote while losing by 7% (it isn't 8% now, is it?) it is at least very likely that he could have broken 60% in a close race. Certainly not ridiculous.
Nym, I'm not sure what you're saying here. While I agree that it is incorrect to say "McCain would've won if not for the financial crisis" I think it would have been pretty close if the financial crisis had not occurred. Obama would, most likely, still have been favoured but not by this kind of margin.
