What exactly will Trump do to end democracy?

As has been said, the main concern with upholding our (already fragile) democracy under a Trump admin has to do with the electoral process and bureaucratic functioning of government agencies. It's not that he's going to be Hitler and send everyone into camps, but that's a very narrow view of how fascism and anti-democratic governing works, especially in the 21st century where you can't hide things the same way you could 80/90 years ago.

I don't even think he's particularly inclined to do Viktor Orban style gerrymandering and various other weird fascist-lite policies. (The people he surrounds himself with in power might, though) I really think the problem is he is acting as a selfish and self-involved person. It's all about him, not about the country. So if someone says something he doesn't like, or disagrees with him, he feels no remorse about throwing them out even if it's a danger to the country. He doesn't like losing and he's going to call it rigged if he (or his proxy candidates) do not win their respective elections. He likes the drama and being the center of attention, so he'll get people to cause uprisings due to the "fraudulent" elections.

Trump has already created a guidebook for how to do things like this. Just look at Brazil after Lula was elected. Therein lies the danger. That's how there's the potential to end democracy. I don't know if he'd be successful per se either. It's just that there's the possibility. Personally, I think DeSantis or in the future a Josh Hawley type is far more dangerous to democracy.
