The “steal” aside, the 2020 election was manipulated into a referendum on Trump’s demeanor rather than the issues. Most of those who voted for Biden were actually voting against Trump and not against his policies.
Let's ignore cheating for a moment. I realize that it is likely that cheating took place. That said.
I know people who voted for Biden in '20 because they hated Trump's personality. They were the same folks who voted for Trump over Hillary in '16. So there you go. Many FReepers won't want to hear this but at times Trump was his worst enemy.
