Inside Parties: How Party Rules Shape Membership and Responsiveness (Cambridge UP, 2025) by Georgia Kernell examines how party rules determine how parties select candidates, nominate leaders, and set policy goals. Most research on party organisation pays very little attention to what happens within political parties; this book addresses this gap by examining how internal party rules and procedures shape party membership and political responsiveness. Drawing on an original dataset of party statutes covering 65 political parties across 20 parliamentary democracies, the book offers one of the most comprehensive studies of party organisation to date. The book develops a formal model of party membership and tests these hypotheses using cross-national surveys, member studies, experiments, and computer simulations of projected vote shares. The book finds that a party's level of decentralisation - the degree to which it incorporates rank and file members into decision making - determines which voters it best represents. Decentralised parties may attract more members to campaign for the party, but they do so at the cost of adopting more extreme positions that pull them away from moderate voters. The book challenges our understanding of inner-party democracy, it reveals that Parties that are more internally democratic don't necessarily end up being more representative or responsive to the electorate as a whole. This novel and comprehensive research is an indispensable resource not only for party scholars but also for anyone working on comparative politics and multi-method research. And for anyone who wants to sneak a peek into the "secret garden" of party organisation.
