Warren's best chance is in a second major party made up of Bernie folks now in DSA. She would face Pence (as POTUS) or Graham (if Mueller fingers Pence) as a minor party and Biden or Pelosi (if she is POTUS or whomever she puts in as Speaker to ascend if Pence out) in the Wall Street Dems (with GOP refugees).
