ABC News sifts through the polling data, turning up this nugget:
It’s fair for the Obama camp to point out that he doesn’t do significantly worse against McCain among working-class whites than Clinton does, and that he does better with their upscale counterparts. And Obama’s numbers are nothing like John Kerry’s and Al Gore’s; they lost working-class whites to George W. Bush by 24 points and 17 points, respectively.
The media has a myopic focus on a single demographic, namely working-class whites, to the expense of a holistic approach. Elections represent a sum of different demographics, not just one isolated bloc. While Obama slightly underperforms in one population segment, he counterbalances that with a strong performance in another. It is critical to view the breakdown of the entire electorate.
