Cheating cost him the election.
There was frustration that he didn’t pimp slap Fauci and fire him. That twerp was pure destruction. he should have been arrested for his illegal gain of function activity, but Trump never had actual control of Barr and DOJ.
And a related problem to not having Barr and DOJ under control was letting the country be wracked by riots and street terror for 5 months before election day. The country would have cheered a hard crushing of Antifa and BLM. There was one weekend in June when he rolled in the National Guard nationwide. That was working hard already and the riots chilled out, but within a day or two, Milley and Barr and all the Republicans in Congress turned against him.
Trump lost nothing. The traitors surrounding him did. He did the best he could, and despite all the treason from his own party, he won in a landslide.
Plus, Nancy holding stimulus up, plus media mocking HCQ, ultraviolet light, and other potential and promising treatments.
