There are two groups here: "World Can't Wait" and the Revolutionary Communist Party. WCW is an "anti-war" front for the RCP. Conyers gave his endorsement and speech to WCW.
And ANSWER, Workers World Party, DSA, SEIU, CPUSA ad nauseum.
That they're not all exactly the same is splitting hairs, and what difference does it make?
They are all rubbing their greedy little communist hands waiting for the spoils.
Hounds of Hell...want a biscuit? Sit.
