Most everyone I know that is not of the left sees him as the lessor of two evils.
Combine that, with the fact the media lies about him constantly, the law-fare clearly going on, the leftist takeover of the deep-state, the made Jan 6 debacle, the economy, social issues and the flood of illegals pouring over the boarders, and he looks pretty good to a lot of people.
Not to you and other leftists, but to a lot of people.
Biden and the left cares nothing about the "average American working man", and in fact has contempt for him. The average American working man knows this, and that is why he supports Trump.
Just look at who supports Biden, and who supports Trump.
