This small anecdote from this post accurately captures the mood in Pennsylvania at the moment -
So a canvasser goes to a woman's door in Washington, Pennsylvania. Knocks. Woman answers. Knocker asks who she's planning to vote for. She isn't sure, has to ask her husband who she's voting for. Husband is off in another room watching some game. Canvasser hears him yell back, "We're votin' for the n***er!"
Woman turns back to canvasser, and says brightly and matter of factly: "We're voting for the n***er."
In this economy, racism is officially a luxury. How is John McCain going to win if he can't win those voters?
