There would be no Union of states left in that scenario. You don’t seem to grasp what’s happening here.

Kamala probably wins, little to nothing changes, and Republicans continue as the party of opposition.
Theree will be no civil war. No revolution. Probably nothing really noteworthy. For the sake of America, I genuinely hope they find a real leader who can lift the country up.
