Mobilization of Liberal Strength in the House, 1955–1970: The Democratic Study Group

In 1959 a number of progressive Democratic congressmen organized the Democratic Study Group (DSG) as a vehicle for countering certain conservative biases then present in the decision-making process in the House of Representatives. This paper presents brief descriptions of the difficulties faced by these congressmen in their efforts to pass more “liberal†legislation and of the organization and activities of the DSG. The analytical focus is on an assessment of DSG success in developing an effective communication network as a means of achieving its policy goals. The central hypothesis is that this communication network has had an impact on the voting behavior of DSG members. Roll-call data from the 84th through the 91st Congress are examined to ascertain whether longitudinal patterns in the voting of DSG members, non-southern non-DSG Democrats, southern Democrats, and Republicans tend to confirm or deny this hypothesis.
