The problem is that all the larger Blue states have signed on, now you’re trying to get enough of the smaller Red states (who would clearly lose power and influence once it’s passed) to join in. I think the only thing that’s going to save this country will be if enough Blue state retirees move to places like Wyoming (which currently has fewer voters than my former county in California) and establish residency long enough to swap things around. It would only take a few hundred thousand here and few more there to make this happen, so it’s theoretically possibly, although I can imagine the Rednecks would go non-linear if their trailer parks started filling up with “those others”.
And until then…
