Trump will eventually do something that gets between rich people and their money while also being an impeachable offense. The "sane" bussiness republican VP will pardon Trump after his impeachment and have him live out the rest of his life as a fox news call in guest until he died of "old age".
If we're lucky he'll piss off his Russian contacts and end up falling out a window by accident.
More likely is that this puppet will be used by bad actors to advance their agendas and as usual he'll distract everybody from the actual bad shit happening.
