A vital examination of how social and economic justice organizations overcome resource disadvantages and build political power. Why do some coalitions triumph while others fall short? In Power to the Partners, Maraam A. Dwidar documents the vital role of social and economic justice organizations in American politics and explores the process by which they strategically build partnerships to advance more effective and equitable advocacy. Using original data tracking the collaboration patterns of more than twenty thousand nationally active advocacy organizations, Dwidar evaluates the micro- and macro-level conditions surrounding these groups’ successful efforts to collectively shape public policy. Power to the Partners reveals that while organizational advocates for social and economic justice are at a disadvantage in the American lobbying landscape—financially, tactically, and politically—coalition work can help ameliorate these disparities. By building and sustaining coalitions with structures and memberships that facilitate clarity, learning, and diverse perspectives, these advocates can successfully—and uniquely—make their mark on American public policy. Dwidar’s work offers critical insights for scholars and practitioners alike, from groundbreaking academic findings to evidence-based lessons for political organizers.
