Biden would (because the nation no longer puts first "most qualified" as the reason for selecting a candidate) have to choose a whacko for VP. He's old, he's got health issues, and he seems kind of senile, and there are huge swaths of states President Trump won where Biden would've won. That VP choice would steer the nation. I'm just assuming, because political manipulators don't care about the nation, Biden could not run with a white heterosexual male.
Rome in its decline had nothing beyond where we are today.
