Allen’s statement was probably correct, but technically those 80 are socialists. They belong to the Democrat Socialists of America. Maybe some belong to the Communist Party USA but West was probably basing his comments on the DSA memberships.
The Republican Party is Socialist. The Democrat Party is Communist.
The DSA has a long history as a Communist front group. They share membership, leadership, philosophy and more. In the late 90s, the websites of the respective groups were linked and articles cross-refrenced and other evidence of collusion. Suddenly after some exposure, a scrubbing occurred. From that point on, the DSA distanced itself from the CPUSA...though minimally.
The DSA remains a communist front group.
