My bet would be on Kamala Harris or Elizabeth Warren getting the nomination.
The dems definitely want a foid candidate. I think it will depend on whether they think they can win or not. If they think they can win, then they'll run Kamala Harris. If they think they'll lose, they'll probably run Sanders. He can take his curtain call, push the Overton window more leftward, the media can say "Seeeeeeeeeeeee, an old (((white))) man just can't appeal to a young, diverse electorate" when he loses, and that'll leave Harris untarnished for a 2024 run.
If Biden does get the nomination, he will
definitely be the last white male Democrat presidential candiate for at least the foreseeable future. You
have to check one of the diversity boxes nowadays. Harris checks at least 2, but is still your safe, authoritarian, globalist, corporatist democrat. That's why I think she's the favorite.
And to the point of this thread, Biden would be great for the nomination to spite foids, but Trump makes foids saltier than anyone I can think of. Whether you love, hate, or are in the middle on his politics, Trump's election has been great for making liberal douches (which includes 90% of foids) cry. Worth it for the lulz, IMO.
