?Altogether excellent study, perhaps the best history on American radicalism that has been written in the last decade. Dr. Myers has left no stone uncovered and has assiduously followed every zig and zag on questions of policy and tactics. Moreover, her judgments of the dramatis personae are exceedingly shrewd, objective, and judicious. Finally, she has revealed how completely removed the Trotskyists were, and still are, from American political, economic, and social realities.?-The Historian
