One fundamental problem for Sanders remains his inability to win over self-identified Democrats. It was a problem for him in 2016, too, and it’s not clear that he’s improved on that front.

But two-thirds of the electorate identified as Democratic versus less than one-third as independent. You have to win among Democrats to win a Democratic primary.
