I've been puzzled why the DNC chose Slow Joe---and make no mistake, he did not "win" but was anointed. He's old, senile, stupid, groping, occasionally racist etc. The answer, I think, is that he is NOT UNLIKABLE. (And of course the media can cover for those other sins.)
DNC's theory of the case is that they lost 2016 because of Shrill Hill. Too many Dumbs stayed home because she was unlikable. The convention was also shrill/unlikable, celebrating convenience abortions and so on.
Joe is a laughingstock, but no one really hates him (except maybe the girls he groped on camera).
Warren? Klobuchar? Hillary 2.0.
Bloomberg? Billionaire.
Butt-gig? Too soon.
Yang/Gabbard/Sanders arguably not unlikable, but also not loyal.
So it's Joe. I'm assuming Klobuchar was paid millions to drop out. Warren stayed in to do the debate hatchet job on Bloomberg, who can't be bought.
You also saw this in the convention. The not-in-person format was a blessing because many speeches were prerecorded/screened, so they didn't have to worry about the head of Planned Parenthood bragging about her elective abortion.
In fact nobody said much about what they would do, just about how nice and likeable they are and Orange Man Bad. If they can avoid alienating Dumbs and making them stay home, they think they have it wrapped up.
Slow Joe is way better than Sleepy Joe.
One less syllable, highlights how dumb he is. Someone can be sleepy and smart, someone can't really be slow and smart.
People are too afraid of change sometimes, a lot of people who think Sleepy Joe is better, only think that because its familiar
