This should probably happen in most states. Certainly VA- NOVA should definitely be its own state because it’s certainly not like the rest of the state. West Virginia did it, so there is a precedent, but I’m not sure how it can happen.

If I recall correctly, Kentucky also split off from Virginia...
I think south central-south east Illinois has a better reason
