It’s hard to tell with Trump. Were his policy failures due to disinterest in governing and bad staff picks? Or was his inability to advance his agenda because of political weakness? He was clearly isolated and without the support of the elected members of his own party.
How different history would have been had the GOP thrown in with Trump in 2017 instead of colluding with Marxist Democrats to destroy him and the MAGA agenda.
Before Trump came to Washington his attitude towards democrats and republicans alike was the same, F’em both. He had been paying both of them off for fifty years to do business. He knew what they were. He came to Washington and was immediately co-opted by DC republicans. Trump allowed them pick his cabinet and to advise him on the coups and impeachments and Covid. On this forum you saw it. No, Trump can’t fire this guy, no, he can’t hire him, no he can’t override Fauci or Barr, no, he can’t stop our cities from burning all last summer, etc. or he’ll get another unit thrown on the impeachment/coup assembly line. Trump lost control of his administration to the swamp operatives of the DC GOP.
