Given that there is no real separation of personal political affiliation in any community, civil war seems pretty unlikely. Sure, rural areas are more conservative, urban areas more liberal, but that's just a tendency, not a hard and fast rule. Much as I'd like it, a secession by say, California, is pretty much a non-starter. No large group of legislative types is going to want that golden goose gone.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
