Hopefully he'll be behind bars Before then, but If he makes it to 2020..nope.
I sure hope not.
Of the previous five presidents, Obama, Bush 43, Clinton, Bush 41, and Reagan, only one of them failed to serve a full two terms. Bush 41 lost his re-election bid to Clinton. So the previous three presidents and four of the last five previous presidents won re-election.
Taking only this into account, it is clear that being the incumbent carries tremendous advantage. The odds would seem to suggest that Trump has a better than 50-50 chance at winning in 2020.
What I know for certain is neither he nor the nominee from the Democratic party will be receiving my vote.
I sure hope not, I will work to prevent it. I hope he doesn't last full term, much less get reelected.
