If you live in red mid western state your legislature and governor will temporarily fill in and will be there for you. Of this I am sure. But make no mistake the converse is also true, if you live in a blue state, I feel for you. You will be the enemy my friend. Either fight guerrilla style or get to a red state.
If a civil war does break out, there will be no hiding behind any politician, including a Republican/Conservative governor. I think you underestimate the fomenting rage that really exists out here, especially in the midwest whether one lives in a red or blue state.
Using Illinois as a prime example (and since I live here ...) the absolute HATRED of Chicago by the rest of the state would mean a very swift end to anyone who tries leaving it to spread their crap out here in the rest of the state.
I guarandamntee it.
People have this perception that Chicago's a warzone and everyone's armed and shooting each other. Not true. There are a handful of neighborhoods where all the murders and shootings typically occur. Anyone who wants to confirm that can go to SecondCityCop.com for example and see the stats for themselves. There's also HeyJackass.com where even more stats are kept.
These gang-bangers wouldn't last an hour out here in the rural parts of the state. They think they're well armed? ROFL!
Try spreading that Chicago hoodrat crap out here and they'll get shot dead so fast that their own momma's won't remember them being born.
