You kick out the federalist that do things like, investigate overturning elections, and suddenly the midterms are all republican wins.
From there, you have someone who can get power passed to change things like presidential term limits. Now you have a king or an emperor with a bunch of yes men backing him up in decisions. Eventually, they can institute whatever policies they want and force states, by force, to enact what they want with military power and courts who rule in their favor.
Oh, but there are people in the military who will stand up and do what’s right? Well, they will be branded as wackos and enemies of the state who are speaking ill of the totally “legit” election. So they are put in front of a firing squad and all that’s left are those who already believe in Der Fuhrer.
It’s a complete shit show in the making and fucking frightening what they could do with disinformation and no checks.
