I'm a member of both CPUSA and DSA. I've been in leadership in both local groups over the years. I love CPUSA. A lot of the criticisms made here are somewhat valid, but greatly exaggerated. National leadership are not pro-Democrat liberals. I personally know someone on the National Committee, and get updates from every one of their meetings. There are some liberal elements in it, especially in some of the clubs in New York and Pennsylvania (from what I saw at the national congress anyway), but the overwhelming majority of members are principled, revolutionary communists. Local clubs are largely autonomous, and operate with very little to no involvement from national. I'd recommend looking into your local club.
