Who will the democrats run next?

Let's assume that, after their shameful treatment of President Biden, the democratic party nominates Kamala Harris in his stead. 

Then, because tfg does not see other humans as fully human, sees people of color as less-than, and sees people with uteruses as r*pe bait, let's suppose he Gish gallops all over her and stalks her in the debate.

Then, as a result, he completely throws her off her game, and she comes off looking like a shrill, uninformed, weak, estrogen-poisoned, irrational hose beast.

And after this disastrous debate, the democratic party discards her, like Biden before her--not because she's too old but because she's too blAAAAAAAAAAAAAck and too female (without even the luxury of being decades into post-menopause like Hillary).

Then who will they run?

And will they apologize to Joe Biden for discarding him for one bad night?
