Presidents, Parties, and Prime Ministers

David J. Samuels and Matthew S. Shugart provide the first systematic analysis of how democratic constitutional design shapes party politics.

Samuels and Shugart provide an analysis of the way that the separation of powers shapes parties' relationships with their leaders - either directly elected presidents or appointed prime ministers. Their work provides the first systematic study of how democratic constitutional design shapes the balance of power between executives and their parties.This book provides a framework for analyzing the impact of the separation of powers on party politics. Conventional political science wisdom assumes that democracy is impossible without political parties, because parties fulfil all the key functions of democratic governance. They nominate candidates, coordinate campaigns, aggregate interests, formulate and implement policy, and manage government power. When scholars first asserted the essential connection between parties and democracy, most of the world's democracies were parliamentary. Yet by the dawn of the twenty-first century, most democracies had directly elected presidents. David J. Samuels and Matthew S. Shugart provide a theoretical framework for analyzing variation in the relationships among presidents, parties, and prime ministers across the world's democracies, revealing the important ways that the separation of powers alters party organization and behavior - thereby changing the nature of democratic representation and accountability.
