Trump has always been big on loyalty
*************
I’m not so sure its about loyalty. Firing people often makes the firer look bad, especially when you’re the one who brought them in. And Trump hates to look bad. I think that’s a big factor for him.
Its ironic that a person so well known for saying “you’re fired” is so reluctant to do that as president. Just saying.
It sure is.
I might add that staffing has been an unusually big problem for Trump. Obama recycled Clinton apparatchiks. Bush... well he didn't do much.
Clinton is the only one I can remember who came in with his own nearly complete crew from Arkansas. No one had ever heard of many of the people he appointed to power positions. But, a lot of them stuck around for a generation.
Trump not only didn't bring a lot of people with him (Javanka don't/doesn't count), he also inherited had an amazingly recalcitrant Deep State.
I think he made a number of bad picks, but his business and personal judgement may have been of limited usefulness in political selection. He may have had to rely on other people. So Rosenstein gave us Meuller; Christie (a purported conservative) gave us Christopher Wray, who I get a very bad swamp-vibe from.
History will have a field day looking back on this through competing hagiographies.
