I don’t see any legal way such a strategy can be stopped, because it’s all based on “legal” technicalities.
I'm not a scholar in any of this, but I can't imagine the President is powerless to halt such a scheme. I've been given to understand that the Office has broad powers under certain invocations. Even if they manage to get everything rolling in just the right way, there's still a period of time between when the elections happen and when the next president is sworn in.
I cannot believe our government would sit idly by and let this cockamamie scheme just unfold and go, "Damn, I guess it's technically legal." And if they do, then they obviously wanted it to happen.
