They have seen a meteoric rise in recent years. Their sister/front organisations like ANSWER, Codepink, People’s Forum, BTnews have all become household names. When I look at protests in the U.S., it seems so many of them are organised directly, or indirectly, by them. In comparison, organisations like the CPUSA or the DSA are lacking behind.
How and why?
The biggest reason is Sanders called himself a democratic socialist repeatedly and those two words are in DSA’s name.
