It's unlikely to be Harris, even Jim Clyburn - the kingmaker in the Dems who got her the spot and who won Biden South Carolina - has backed the idea of a second primary https://thehill.com/homenews/campaign/4754731-clyburn-mini-primary-biden/
Back when the dunk tank allowed garbage everywhere I was frequently in the comments of posts yelling at people to post that garbage in the dunk tank because I don't always want to see that shit. They either didn't care or forgot, but in either case, it was nice to have a place to point to where I could say "this trash goes there."
But we decided that our trash can is not a trash can and 
Hexbear is shocked that we now have trash everywhere.

Which ones did they block?
Biden clearly never learned anything from Obama - if Trump is so evil, just declare him a terrorist and drone-strike him 
Kamala Harris is the most likely pick. She was pushed for by Jim Clyburn, and his endorsement is what handed Biden South Carolina, and he has a lot of sway with black Democratic voters. Passing her over would be seen as a snub to them and that's a major Dem voting block that they can't afford to alienate. But she has negative charisma and the White House basically shoved her in a closet to do nothing so she doesn't have much to show in the way of accomplishments. And she's awful in debates - better than Trump or Biden but anyone who remembers the 2020 primary remembers that the only thing she did was torpedo Biden's standing and then getting smacked around for being a cop.
Gavin Newsome (governor of California) is a big deal in the party but "governor of Commiefornia" is a position with a lot of heat that might not play well in swing states.
Personally I think Dems' best shot is Gretchen Whitmer (gov of Michigan) - midwestern, has a bit of a name on the national stage from being targeted by CHUDS for assassination so she'd have a lot of cred in the fight against MAGA. Josh Shapiro (gov of PA) is floated a lot too, but I don't know much about him.
The funniest option?
