here are the latest polls on the primary
notice the latest poll from politico seems post-debate
harris 12 (doubled her numbers)
everyone else 1 each
a biden-harris ticket, assuming they can kiss and make up (im sure uncle joe would be into that, lol) adds more than other possible pairings (i don’t see a biden-bernie ticket happening)
notice also mayor pete is for public option not mandatory single payer. as i think also is beto.
