This book investigates the often-overlooked influence of local party organizations on electoral outcomes and candidate selection processes. The authors, David Doherty, Conor M. Dowling, and Michael G. Miller, utilize a combination of survey data and empirical analysis to map the activities of local party chairs. They argue that these grassroots entities serve as critical gatekeepers, shaping the political landscape through recruitment, financial support, and the vetting of candidates based on specific demographic and ideological criteria.

Experts identify this work as a significant contribution to the study of American political infrastructure, noting its focus on the micro-level mechanics of party organization. Readers frequently highlight the clarity of the data presentation, which makes complex political science research accessible to students and practitioners alike.
