> people are nervous that this is becoming true

It seems abundantly clear that there will be no peaceful/rule-of-law transfer of executive power in January 2029 to anyone but a hand-picked Trump successor that wins an election. A democratic victory (or even a Republican primary winner that isn't appropriately selected) will be resisted at all levels of the executive, and... we'll just see. Whatever the result, the losing party will call it a coup and illegitimate, and such an administration will survive only so long as it can hold control of the government by authoritarian means.

It may even happen earlier. A lot of the kerfuffle around redistricting is being presented to right wing audiences in a way that would be very easy to spin as "cheating". What do we do if democrats win the house next year and Johnson simply refuses to seat the California delegation to keep power? Are we prepared?

Basically, the End of the American Experiment may have already occurred.

I'm not so quick to pull the trigger on that assessment. I think we're at point where the rubber band has ostensibly been pulled back nearly as far as it can go, and it may snap, or it might make a surprising move in the opposite direction in response to the tension. I don't think any of us peons has any meaningful control of which of those two things happens, but I think it will hinge a lot on how much big businesses are affected by the economic and political consequences of recent policy moves. No matter how much Trump might bluster about big businesses and such, he'll still fall in line if enough get pushed to the point of having to draw a line in the sand. Too bad it will probably be big business operating in pure self-interest and not some actual principled entity. Maaaaybe if there's enough economic pain among his base, that could point us towards a voter-driven repudiation to some extent. Even if they cement their power significantly, I don't think they could swing it with an outright rejection of their approach. I doubt that will happen though.
