Yes, we know why. However, I do think the majority of those who actually did vote "for him" were actually votes against Trump & conservatives. They have no interest in Biden, but were/are resisting anything that isn't radical left.

People ask me all the time how Bill Barr got it so wrong. Barr was told by his advisors that he was a rising GOP “star” & could even run for higher office if he “stood up to Trump.” That’s also what happened to Mike Pence. That’s also what happened to Liz Cheney.
Plus many folks don’t even know they voted for Biden.
