Someone call Hilary!
But seriously they've fucked themselves making Kamala VP. She's a woman and black so the optics of dropping her aren't going to look very good and no doubt there will be those who will bring that up.
Also the new president is sworn in January, raises questions as to who is running the country right now because it doesn't seem like Biden is fully there. Hasn't been there for a long time and those who pointed that out were shamed for doing so but now it has become so obvious even Democrats can't spin it.
