The neat thing about the US is that governments are overthrown regularly by automatic operation of law: 12pm on the 20th of January 2028, in the case of the 47th president. I'm sure you know this but I feel everyone needs to remind themselves of this immutable fact regularly until then.
Do not make the mistake of believing laws are as concrete as code. There are many, many instances throughout history of the powerful people who are responsible for enforcing the laws, deciding to suddenly change or ignore them.
You are 8 months in since your last 20th of January and your chief turd already collected all top military officials and started his speech by intimidating them. There is no such thing as "automatic operation of law".
An "overthrow" would be highly undemocratic and it's very curious to hear the same people that claim Trump is literally Hitler talk about "overthrowing" their (democratically elected) political enemies and then "punishing collaborators". Is there no sense of self-awareness at all?
The majority, of course, can decide to get rid of democracy and transform the country into a fascists dictatorship. But in this case they can't expect democrats to treat them by their democratic rules. This is not how it works, sorry. Your self-awarness is broken, I'm afraid.
