There is no rational way to split the country, even with a Civil War 2.
Along what lines? Political parties? Political ideologies? Cities v rural? States?
One problem with splitting is that the Liberal/Leftist/Socialist side needs money from the others. They eventually run out of their own money.
Another problem is that too many from the Californias, etc., have moved to other states. Why are they leaving paradise? Then, they are slowly turning those states purple and blue. So will we need armed borders or wall to keep the 2 separate?
It would have to be States. Texas for ports, the Midwest and Southern States can be the United States. East Coast, Cali, some Northern States and probably a couple Southwest States can call themselves whatever they want. Freakistan sounds pretty good to me.
we'd have to have some kind of law that citizens of the state get the first rights to buying land/farms/houses/businesses within the state, and secretly, we'd have to only sell to fellow patriots...
