The fact that Biden (or his handlers) even selected Harris for VP shows that their heart isn’t in the race to begin with and knew that Trump was going to win.
It is unlikely that democrats would plan to fail; I think they thought that Biden was the heir apparent, since Hillary is unelectable, and that they would kill two birds with one stone by selecting not only a woman, but a woman who is black (or close enough that they thought they could fool the black demographic they depend upon so much). The fact that she’s condescending and has a lousy record with blacks, from her days as a prosecutor, probably never crossed their minds.
And as for the other two black women they could choose from, Stacey Abrams and Michelle Obama, one was ugly and abrasive, and the other had no interest (thank God) in becoming vice-president OR president.
To flaming conservative:
I think you meant to say one is ugly and abrasive,
While the other is abrasive and ugly, but also abrasive and abusive.
But nobody is perfekt
