Likely more like Chicago against downstate.
“CWII will not result in one geographical State against others.”
Agree.
More likely rural vs urban, and more like an asymmetrical guerrilla war of patriots vs central government. The best outcome in this scenario would be destabilization of Leftist government with a constitutionalist military strongman taking over and hopefully transitioning back to a constitutional republic as much as is possible. But, the temptation for reprisals against the Leftist tyrants would be very strong...but necessary, IMO.
I tend to agree on more of an Urban vs non-urban standpoint. All you need do is to look at the red/blue map.
Article is BS. State Governments are the next logical political entity after FedGov™ collapses. The republic was designed that way. Yes urban areas are liberal but most (red)state governments are conservative and will quell the urban problem in those sates. The chaos in blue states is their problem.
“More like Chicago versus downstate.”
I agree. But the funny thing is I live in DuPage county, once red but turning purple suburbs of Cook. While I would side with the downstaters, it might be against my own neighbors.
