I don't think Trump will finish out his term. I suspect that after a year or two, he's going to get bored, he'll get frustrated with the inaction of Congress, he'll realize that the 'blind trust' that he placed his assets in is not producing the 'wealth' that he thinks he could build on his own and besides he'll feel that the Presidential salary/expense account is not adequate to support the lifestyle that he and Melania have come to expect and with his assets tied-up in the 'blind trust', he'll start to feel 'poor' and that he will not be able to live with. Besides, there were numerous reports over the past year or so that he, during a candid moment, indicated that he didn't really want to be President. Another thing, he is very dedicated to the well-being of his children so that when he realizes that he can't give them government jobs (there's an anti-nepotism law passed in 1967 that grew out of Kennedy appointing his brother as Attorney General in 1960) and that any 'blind trust' would have to also lock-out his kids from managing and influencing how the assets are invested, that this will also sour him on the idea that being president was a good idea at the time, but that he had never really given it any detailed thought as to what the real impact would be on him and his family personally.
Also, once his supporters realize that very little of what he promised will ever come to pass, that they will turn on him and he will not be able to endure that since he needs the cheering crowds to feed his ego. And then there's all those skeletons still buried in his closet, any one of which could potentially bring him down. Let's not forget, as far as the GOP is concerned, and this includes the House and Senate leadership, if they had their choice, they would rather see Mike Pence in the Oval Office any day. So if something were to blow-up which lead to an embarrassing situation resulting in a Constitutional crisis, the Republicans might just support "doing the right thing" and remove him from office.
And even if he did manage to hang-on for two years, it's a historical fact that a new President will not do well in the first mid-term election cycle and with the House and Senate closer matched than even the last time around, he could potentially lose control of either or both chambers and then, to him, his life would be holy hell.
