Nobody said the president will just remain a president if he just says so. What I originally said is that the fact this (the acting president refusing to go through peaceful transfer of power) is a serious discussion is symptomatic of a serious issue, and I maintain that, and nothing you said contradicts it. You then replied with a weird tangent about Obama.
You should note, the man has shown many times to be able to gather a crowd of hundreds of thousands of people with a few tweets, and phone calls.
It won't be a matter of a few secret service agents escorting Trump out. It will be a full on armed standoff in the white house with 40% of the country rooting for Trump.
Top that off with a raging pandemic, unprecedented economic devastation, homelessness, shutdown schools, and sophisticated digital propaganda campaigns designed to exacerbate every divisive issue and it is hard to see how US democracy survives.
If the secret service can't cope with a few protesters what is the point of them?
The peaceful transfer of power is about the operation of the government transferring - the head of the army, the secret service, the finance, etc.
You might get civil unrest if some Trump supporters refuse to accept it, but unlike other countries where ballots are counted, the US does not elect a president by popular vote, instead a joint session of congress counts registered votes from 538 electors across the country. The sitting president isn't even the room. There is no question.
