I know I can get apocalyptic sometimes with my political predictions, but Trump deciding to defy the 22nd amendment and run for a third term in 2028 is pretty much all that is needed to end American Democracy isn't it? Cause if he can get away with it, and he will, why wouldn't the next guy do it too? We will be stuck with Lifetime Presidents who win their "elections" with 90% of the vote just like Putin, KJU, etc...

Is there anything that can prevent this? Other than a surprise upset from Biden?

If the Supreme Court were just going to let Trump do whatever he wants they would've overturned 2020 for him.

At this point both sides are concerned the other are authoritarians who want to end democracy, personally I think there's a higher risk that the left decides their socialist views are so correct and their utopian plans for the humanity are so pure that they can't let elections mess them up for another four years anymore like 16-20. If having a permanent one party means getting their way on gun control, universal healthcare, abortion, affirmative action, climate change, etc. instead of those evil conservative views, maybe those leftists would be killing to break a democracy egg to make an omelette.

Nah, when Democrats have power they are far more neo-liberal than anything conservative. Admittedly Joe Biden has been very New Dealy ala US presidents of the the 30s-70s but this is hardly socialism.
