I’m not going to attempt to draw the borders here, and as of even a few weeks ago I didn’t believe this, but I think it’d be better now to divide the US up into three countries, with some caveats:
First country: Jesusland, encompassing most of the South, Idaho, North Dakota, South Dakota and the like.
Second Country: Cascadia, which would be California, Oregon, and western Washington.
Third Country: North States; New York, Massachusetts, Connecticut, Vermont and the like.
None of these ideas are new, of course. The problem is letting Jesusland have nukes, primarily. That would be bad. Very bad, and hard to see how to avoid it.
Assuming the nuclear weapons problem could be solved, there should be a heavily-enforced five year period where anyone from any of the three new countries could freely migrate to any of the others, and be provided a stipend and some form of decent housing until they get settled. Without this my idea should be off the table.
Of course, Jesusland probably would not and could not provide this, but at least the North States and Cascadia could offer this for those fleeing Jesusland.
America would fight another huge civil war before this would ever happen, but that still doesn’t mean it should not.
