Judges simply shouldn't be nominated by one single person, particularly if that person is the de facto leader of his political party. And confirmation of judges simply shouldn't be possible purely based on how many seats that same party holds in the Senate and, in a worst case scenario, without any kind of bipartisanship purely along party lines.
Because that essentially means that Supreme Court judges are nominated and confirmed by the political parties.
Apart from maybe a president being able to single-handed determining Supreme Court judges, almost any other system would be better. Including - as shitty as that would be - direct election of Supreme Court judges by the entire electorate.
That's because every single person who slights him even the tiniest bit was obviously always his enemy, and he obviously always knew this. Probably a RINO, a secret Democrat, a stealthy undercover deep state fake Republican. Very bad person, could not be trusted, in fact Trump barely knew them, they begged him for the job, but they simply weren't up to it.
Even if he praised that same person to high heaven just the day before.
Evidence: the 263 people he hired and fired in the last administration (with the firing usually done via Twitter, when they were far away from wherever he was tweeting from).
