Ramsey Clark? I might have known.
Clark is the closest thing to an American Communist kingpin that we've got right now. His fingers are in a lot of things that can't be described as anything but anti-American, including a position of major influence at A.N.S.W.E.R.
And John Conyers is a socialist, by any rational definition, figuring prominently on the Democratic Socialist web site before they got a clue and snipped many (but not all) the obvious connections between themselves and the "Progressive" Caucus. They're getting a little shy about advertising the Caucus as well--apparently the website hasnt' been updated for a while.
The DSA's opinion of the Democratic Party.
