I saw you wrote this earlier today on the NPR Poll: "The poll, taken between 9/18 and 9/20, also shows that Wal-Mart shoppers prefer John McCain, which would seem to contradict data showing that voters making less than $100,000 a year support Barack Obama."I believe the simple explanation for this is demographics. There are no Wal-Marts in major metropolitan areas, and if they are, they are on the edges. And if the target of your poll, those who shop at Wal-Mart, excludes most people in metropolitan areas, the democrat is never going to lead that matchup. It's like polling people who use subways and being surprised that McCain is trailing. They should stick to just looking at actual income levels.
