What does Kamala offer a ticket when she hasn't moved the dial at all. People see through her, and she hasn't been able to connect with black people.
If you need a black person for the ticket it should be Andrew Gillum or Stacey Abrams. Gillum is def the best choice for Warren but I could see there being negatives for Biden picking him. Biden's age is a concern and nominating a mayor as your VP could be questioned in terms of his readiness.
Honestly I don't think any of the candidates are good in terms of electability. People say Warren would be great for the base but...black people are clearly not fukking with her. Maybe that changes when she becomes the front runner in a few months. Also I'm not sold on her winning in the Midwest. Barely anyone is talking about the Midwest outside of Pete, but there's no path to winning unless you retake those states that Obama once dominated.
