It seems pundits have a habit of referring to Pennsylvania with a phrase that goes something like "Philadelphia on the east, Pittsburgh on the west, and Alabama in the middle." The obvious problem is that this isn't true. Obama won Alabama, remember, because there are a lot of black people in Alabama. If the point you're trying to make is that there are a lot of conservative white people but not a lot of black people in central Pennsylvania, Alabama is actually a pretty terrible comparison. Why this keeps getting repeated is a bit beyond me.
