I'm not sure how a peaceful split up happens when everything and everyone is so entwined. But if the Federal Government left decisions up to the states, it would accomplish something similar and those who liked left leaning policies could move to those locations, and those who liked right leaning policies could do the same.
The Federal government would just have to butt out of everything but what it was designed to do in the Constitution.
As much as the left and the right hate each other I think they could make it.Give conservitives all the Confederate States,Wyoming,N Dakota,split the swing states,split miltary assets etc.
Its the rich and big business that wouldn't want the country split imo as its good for them how it is.
