I think that a lot of it comes down to Trump receiving (intentionally) bad advice and then deciding to go along with that bad advice. I don’t know why, but he does. There’s obviously still people in the administration who are willfully trying to sabotage his presidency. I even hear that about his Chief of Staff, Susie Wiles. She’s not letting some of the people who would give him good advice to have access to him. Things are better than they were in the first term, but not by all that much.
