Please remember that Donald Trump is a novice in government and because of this relied and probably still does rely mainly on advice from other government employees who are entrenched. He takes advise from the Deep Staters because there is nobody else and it’s only after having them on board for a while that he may be able to learn enough about them to come to his own conclusions.
Trump doesn’t have much to choose from in government. About 95% of money from government workers goes to Dems.
