I agree with you, but at the same time I can't think of any other candidate that would both (1) have enough name recognition to motivate semi-apathetic democrats to vote, and (2) not rile up the semi-apathetic bigots into counter-voting.
According to the gossip, Biden has said that if he does choose to step down, he'll promote Harris. I don't think Democrats will have much of a problem supporting Harris, but I'm concerned being a woman of color will motivate a lot of bigots into a counter-vote when they might have otherwise stayed home. The next best pick might be Buttigieg, but then you get the homophobic bigots coming out for the counter-vote. Newsom might be the next best after that, but then you have the anti-California lunatics coming out to counter-vote him.
As much as I don't want to cater to bigots, I think the stakes are just too high here. If it were a campaign against Mitt Romney then I wouldn't think twice about running any of these people, but when we're on a razor's edge against America spiraling into a fascist dictatorship, every risk needs to be accounted for.
Obviously Biden should've declared back in August that he wouldn't run for reelection so the Democrats could run a primary and build up someone to have name recognition and a positive image, but now it's too late for that 🤷♂️
Being unable to give an actual example proves you're just a foaming-mouth hater with nothing to contribute.
