This is exactly the two-state solution the administration/regime seems to be working hardest for.
I don't think the progressives are considering a multistate result. I think they're convinced they can crash the US economy and install their "utopia" in the rubble of America with, of course, them holding ultimate and unchallenged power, and any elections that will be held after that will be a sham. But I don't think they're even thinking they could crash the whole thing and not come out on top of the whole enchilada.
