I'm not so sure those people were "mistakes" as such, President Trump came into DC as a total outsider, to some extent he needed some people who knew how the system worked until he could get his feet on the ground, I'm sure he had a pretty good idea of who he could just turn loose and who needed an eye kept on them. He also seems to put people in positions temporarily to accomplish certain things. Bolton for instance, his solution to everything is to start yelling war, between that and that cheesy mustache I call him Yosemite Sam. Let's say you are trying to bring a somewhat hostile leader to the table, you are holding out an olive branch, meanwhile your adviser over hear is hollering and raising Caine about how we should be dropping bombs on this country. That leader sits back and says maybe I better listen to Trump before he starts listening to Yosemite sam.
Exactly; when he took office..the democrats considered him a "the enemy", while the republicans had many deep state operatives already in place. Perhaps Trump's biggest mistake was underestimating just how many enemies of the US were already in key jobs, and so took advice from people he SHOULD HAVE been able to trust !
When he gets re-elected, many of those self-seeking individuals will be gone, so more can get done in a positive manner.
Sure, the Democrats will be up to no good for the entire next term, but if we can have both houses and the presidency for 4 more years, much good can be done.
The future concerns me though, because at some time, the democrats will have control, such as they already do in California and New York.
...And since they are bent on destroying the USA, they will do much damage as soon as they are able !
