I disagree about article being irrelevant.
The fact that those trends where Democrat base (uneducated working class people) was Leaning McCain when compared to Obama and Leaning Hillary when Compared to McCain, it is clear that Obama is bound to lose that CRITICAL segment of the Dem Vote. Thus he can not carry Industrial midwest.
The fact that analysis is based on Poll BEFORE Snobama-Gate, only means that margin in favor of McCain would be wider.
To that extent, I concur with you.
Exactly, unbeknownest to the punditry, the battle lines for election 2008 are being drawn:
Obama the Elitist
v
Mad John McCain, the War Hero
It may not be irrelevant -- but it's almost irrelevant. It's based on a poll of registered voters and not likely voters. Registered voters are a very undependable lot given that only half of them actually bother to vote.
