ACP/NBC:Clinton polls like Obama 2012, geographically (cities/rural/'burbs/etc.)

[Linus Van Pelt]

If you read methodology at the above link carefully, the four categories listed don't cover the whole country; there's some odd sampling of counties in certain regions going on. So not all rural and exurban counties, in the intuitive sense, are included under "rural" and "exurban", and I'd be cautious about concluding that this really shows one to be more Republican than the other.
