Look at it this way. If Trump picks and allows to stay in positions people who are clueless or derps, what does that say about Trump and his advisors?
Trump had no problem firing Mattis or Tillis when they bucked his plan. Or Kirsten Neilsen. No problem at all. That should be a good clue.
I know that Sessions was the first person in the Senate to back Trump, which was good, Sessions has a great Rep. in that position...
No he didn't have a problem firing people, he has never had that problem, but at the time of Sessions wasn't Rence P. talking into Trump's ear???
I don't know, but I know Our President doesn't make mistakes, so there is that also...which leaves what???
