Perhaps that's because Biden is a good guy while Trump is a malevolent narcissistic psychopath who will say or do anything to further himself to the detriment of anyone and everyone? Just a thought.
Really it comes down to this for me. Is Biden the ideal candidate, not for me. But I do believe he will do what he believes to be in the best interest of the US, whereas the current occupant would step over each of his kids for his own self interest.
