This article traces the history of the Office of Economic Opportunity/Community Services Administration, focusing on Richard Nixon’s failed attempt to dismantle it in 1973 and Ronald Reagan’s successful effort in 1981. I explore main two main questions: Why was Reagan able to succeed when Nixon had failed? and What does the dismantling of the agency reveal about the development of American conservatism in the 1970s and 1980s? Drawing on original archival materials, I argue that the Reagan administration learned from Nixon’s failures and adopted a more professional, managerial stance when it dismantled the agency in 1981. In addition, recent work in history and political science has explored how the multiracial democratic vision articulated by LBJ’s Great Society helped fuel the modern conservative movement. By focusing on the long-term opposition against OEO/CSA, this article provides new insights into how conservatives articulated an alternative ideology to postwar liberalism.
