He is removing anyone he does not consider "loyal" to him, so will end up surrounded by yes men, like the weakest dictators all over the world who don't allow any other thought except his. Then he wants to dismantle the judges, as the supreme court - which he has still stacked but are more independent than other places - will be the final piece to fall. Tariffs are all a distraction, but one that is heavily damaging.
This is the nature and way politics works, is any politician kind or naive enough to keep disloyalists or allies of the opposition? Isn't that like shooting yourself in the foot? The same thing will happen if the Democrats take over the White House, they will also remove those close to and loyal to Trump.
he is not looking for zombie yes-men. he is looking for people that just get on with the job at hand and dont backstab/do the opposite
there are people he chose that were not 100% trump supporters but he knows they are going to get the job done
(remember how even elon banned trump from twitter)
just look at the difference between last administration vs this one..
trump is trump, but this time round everything seems more organised, even his speech writer are keeping trump on-topic, things are actually getting done, theres no backstabbing within his cabinet members. its just done as asked and move onto the next mission/task
the first administration seemed more like he just wanted boot lickers/fans working for him. but this time he wants those that know their job and can perform. obviously he wants those happy to work for him rather than oppositionists. but thats different than just employing a bootlicker this time
