Students of the Socialist Party of America are well-acquainted with the extensive and persistent support it received from poor farmers, many of them tenants, in Oklahoma and Texas. David Shannon and, more recently, James Weinstein have both noted that the Socialist Party of Oklahoma had a more active and widespread membership than any other state branch of the Party. Both writers have also given proper emphasis to the shattering impact of repression upon the widely scattered and vulnerable Socialist locals in the rural areas of the Southwest after the United States entered World War I. Weinstein especially has suggested that the Socialist Party was a broadly-based and effective political organization, not only ‘in’ but ‘of’ the world of American workers and small farmers. Pointing to the vigour of the Socialist Party's support in the North and East after it opposed American participation in the war, Weinstein argues that an American Socialism attuned to American conditions and needs had much potential vitality and could have been a significant political force in the country. For this assertion Weinstein was sharply criticized by a reviewer who argued that he exaggerated the depth of the Party's support after 1912 and that he specifically failed to perceive the German ethnic origin of much of the Party's ‘new’ support for its anti-war position.
