Yea, the concentration of Democratic voters in the Los Angeles slums, in Detroit, Newark, Harlem, and Washington D.C. really reflects this difference: Republicans really appeal to the coarse and uneducated and Democrats to the enlightened. Do these people ever leave the Upper East Side?
My parents recently went on a sailing cruise in Maine. One of their fellow cruisers was a NYC liberal. While this guy travels, he never really leaves his liberal bubble. Just flies from one major city to another. Perhaps an occasional weekend in CT.
He was annoying to all the passengers. Once he found out that my parents live in Ohio, he kept asking them how anyone could support Bush when kerry was obviously the better choice.
