If that should ever happen, the country will split into at least 2 pieces, just as did India (when the Muslims and Hindus separated) and Yugoslavia (also when the Muslims and Christians separated).
Whether such a US split would be a good thing or a bad thing is debatable. One could argue that the US is currently too big and too polarized to be governable.
The bad thing is, conservatives and libtards are scattered everywhere. The mass migration might be as troublesome as that which occurred in India and Pakistan.
It’s worth it though, to be rid of the godless, vile, lawless libs and their foreign spawn!
