The biggest fear and problem I have with the coming CWII is that in the 1800's the sides were drawn up geographically. This time, it will be ideology. And there are Conservatives living next to liberals.
It can't be a very long one based on the fact that there's little room for sides to form up nowadays.

Its still geographic - just look at the county-by-county election map. Sherman's tactics would be appropriate in some cases. Conservatives in the countryside would most certainly take in those stuck in the deep blue zones.
