Oh, sure there is. There's the coathanger Left, the manbashing Left, the America-bashing hang-Bush-in-chains Left, the tree-spiking Left, the laboratory-wrecking, antihuman PETA Left, there's the pet-eating carbon-footprint Left, and the plain old "let's just ignore all the other bushwah and get down to it" Stalinist Left.
Those white liberal crackpots at best would fit into the Superdome.
