That’s because her message about disenfranchisement seems to have taken hold. As Ms. Williams noted, there are still 10 contests to go, with perhaps 43 millions votes to be counted.

Thousands of people are coming to her rallies now, and her campaign has organized events in post-Pennsylvania states where people are thrilled to be part of a process from which they are normally excluded.
