from above, parte due ---
 I don't think it is fair to expect Trump to get rid of his businesses in such a short time. It is impossible to shed so many big businesses that fast he would take such a loss and it's just not possible to do that fast in a legal fashion. 
So do I think he will ever divest himself -- NO. 
Will he be totally uninvolved in his business -- NO. I believe he will profit from his businesses and be president for his businesses -- YUP. 
Is Trump a supremacist? YUP, both he, the Right and the RRs (including Card. Dolan,etc). 

But what is or may prove to be the real true question about Mr. Trump. BTW< I liked much of his speech but not all. A few items were scary/frightening.
So okay what is the true question: is he a populist? OR, is he a far right Republican populist???
Very soon we will know the answer.
The other possible question is : how soon will it be before the American Catholic prelates begun to waffle, slip and slide on their huge support for Trump.
