What Trump should do is take a set of "bums in the streets", get them clean and appoint them into important political positions that all Americans can see, and let these people talk about their new life. This would hit a nerve of all the establishment.
For Diplomat appointments, this is his chance to show how much he likes woman: he should appoint ALL women around him as diplomat somewhere. If there is not enough, he should find as many porn stars as possible,
and appoint them there. That would hit a real nerve with the establishment. The most sulfurus one should be sent to Middle East countries. That would really piss ME people to have to bow to a woman - and a porn star at that - to get a visa. I'd bet the number of applicants would decrease.
For Department of health, Trump could search for all these alternative health people, and appoint one of them as head of everything health. Just in passing, I am against pills and all for natural healing methods.
What he could do is appoint these people for 6 months, as then they'll normally have life salaries as they once in their life get these jobs. Then appoint another set from the same type few months after. hahahaha
That would really upset the establishment, but please the crowds. But I believe Trump would not dare to do something like that, lest he wants his youngest son dead. I am sure he would not mind for his own life, but I'm sure he'd mind for his youngest one.
