what are some of the traditional political divides within states

[nclib]

NC and VA also have somewhat of an east-west divide with a heavily black and democrat tidewater area and a more republican mountainous western area

In NC, this has more to do with race than ideology. There are very few white liberals east of I-95 except right on the coast. Next week, it will be interesting to see the anti-gay marriage (and civil union, etc., but I digress) map, I bet the anti-gay support will be stronger east of the Triangle than in the mouintains.
