@endicom @Quix @Freya I have already written about her second and third way and I have another.
Her second way is impeachment and that could happen if Trump does something drastic that is criminal, against the law, something egregious the country cannot abide. Something so terrible even the Republicans are willing to start impeachment.
Her third way is the 25th amendment and that could happen if Trump has a mental breakdown and can't function, which I believe is possible. His emotions are always on his sleeve and he must attack people/countries/foreign leaders, every day who have the slightest objection to something he does, and now has to do it 24 yrs. a day as he sees the non-stop public objections to him across the country and from other countries/leaders.
Another way is if he has a physical breakdown which I think is possible since he only sleeps 3-4 hours a night and in this 24 hr. job, his brain/body can't take it and he has a heart attack or stroke - his body shuts down. That would also invoke the 25th amendment.
