I disagree, other then the mid september surge, biden has been leading practically every poll since he got in. I don't think it will be a mixed gender ticket either, part of "normalcy" will be two boring white guys talking about the economy. Kamala or Stacy are not "back to normal" for moms in suburban Chicago or Detroit. Ryan brings Ohio, Moulton is a vet and Bullock doubles down on experience and covers Biden on domestic issues. And I don't want to hear it from black people when it happens breh, because black people will have chosen that ticket.
How can we complain about representation or whatever when given the power, we choose the same. Can Biden win? Yes. 40 States? I believe so. But it shows we have learned nothing from the Trump era.
Even if he doesn't win those, he's still in line to clean up on super tuesday. I say this as someone leaning warren right now.
