Today Dolores Huerta a long time Latina activist endorsed Kamala Harris and her race for POTUS.
Even though Ms. Huerta is from California she has an impressive history in labor organizing and farmworkers. This is a big endorsement and continues the momentum for Senator Harris that began with her announcement.
As of this moment Julian Castro does not appear to have any momentum but as we have all said it is early.
