There ARE no pro-Biden people, ONLY anti-Trump folks. You never hear someone say, “I really like Biden and his policies.” What you only hear is, “I hate Trump.” That’s why the Biden campaign has to focus on hate and fear. There’s really not anything other than that to lead one to vote for him.
Voting for Biden is the ultimate empty-headed, knee-jerk “reactionary” move. And it is often, at heart, a cultural issue, not a reason-directed one.
