This concludes part 1 of this essay, addressing treatments of the national SPA, its leaders, its theory, and its relationship to national politics. Part 2 will examine more narrowly defined studies of the SPA’s activities in specific cities, states, and regions; its relationship to particular civil-social constituencies; and its significance in the lives of individual intellectuals, organizers, and officeholders who once championed the Party’s politics, forthcoming in the May 2022 issue of Choice.
