It’s a Good Thing that the Moose Shell was not interested.
I suspect she really IS interested, but decided she had a better shot in '24 than '20. In her mind, Biden is toast, along with anyone who throws in with him. Kamala and Stacy are the only ones stupid enough to take that chance.
Just a guess on my part, I could be wrong. Let's see how energetically Barack campaigns for Biden - if my guess is right, the Obamas need Joe to lose convincingly.
