Video of a discussion of Jack Ross's History of the Socialist Party. A massive book but this discussion might get you out to the Library (or store) for a copy. It's well worth the read IMO and dispels some orthodox interpretations of recent American History.
Jack Ross talked about his book The Socialist Party of America, a critical history of the Socialist Party of America. Commentary was provided by Eric Arnesen, J. Arthur Bloom, Ernest Evans, Samuel Goldman, and Jon Basil Utley.
