Let’s face it. Trump lost. Voters were more concerned with his personality than accomplishments.
Trump won 10 Million more votes in 2020 than he did in 2016, the most votes for a sitting president in US history. More votes by far than Obama in either of his races. That doesn't quite fit with your analysis.
Additionally, Trump won all but one of the 19 bellwether counties. Biden only won one. A Biden victory, by any means other than massive voter fraud, is the height of absurdity under those circumstances.
