What you’re not seeming to take into account is that every democrat I know has issues with Biden but since he is a career politician we know he’s capable of putting knowledgeable people in places he doesn’t have expertise in, which is what a competent leader does (which means I can’t even mention trump, doesn’t come close). The right doesn’t seem to understand you can get your ideas and policies across without full complete love and support for the candidate. He’s not the Dems supreme leader like the right has where everyone has to bow down, it’s a system and he’s just a head to rally behind while others get stuff done.
Except it wasn’t pure luck things worked out for Trumps term regarding the SC appointees. Obama was able to pick one or two which was blocked and vetoed and filibustered by the cons for years until their guy was there.
