The second Civil War, I’ve often wondered what that might look like. Secession of states currently with a constitutionally oriented administration (Trump) the only state that might do it if provoked sufficiently is California. (Arrest of Brown, state & city officials for violating federal immigration law might be sufficient!) Now I could be wrong about this, but I don’t see the state legislatures of Washington, Oregon, Illinois & New York as sufficiently full of enough crazies to pass an article of secession. So I think it would be a short civil war, I don’t see California National Guard units lining up to support Brown & company. I do see Brown & company (Hollywood, etc.) resigning and trying to promote an insurgency that is centered in the big cities. I don’t think it would last long and it might not look any different then the LA (Rodney King) and/or Watts riots.
Likewise in the other states I could see a “insurgency” in the major cities. Again it might not look any different then the riots of 1968, etc. The question is ‘Will a Trump (or Pence) administration lose their nerve and not tamp it down immediately?”
The leftists have one enormous advantage over us Conservatives/Originalists, the organization and ability to mobilize an "army" of mindless drones at will.
