Rainer Shea is a patriotic socialist who made a hard turn to condemning the PSL at every opportunity after they failed to support his "anti-war" rally with Tulsi Gabbard, Jackson Hinckle, and the Libertarian Party USA.
Brian Becker is one of the most principled communist leaders in the west, and is so frequently portrayed as a "Russian asset" by liberals that the underlap with Rainer's claim here is just funny.
