So to sum up:
Two new national polls, I showing Biden with a narrow lead, the other showing Sanders ahead
Five new state polls, two showing Sanders ahead, three showing Biden ahead by an average of 8 points and Sanders # 2.
There is no evidence that Elizabeth Warren's claim that Bernie Sanders told her in 2018 that a woman could not be elected President is negatively impacting Sanders in the polls The debate seems to have helped Sanders. Over-all January is shaping up as Sanders' best polling month yet.
