Legislatures are arguably the most important political institution in modern democracies. The Oxford Handbook of Legislative Studies, written by some of the most distinguished legislative scholars in political science, provides a comprehensive and up-to-date description and critical assessment of the state of the art in this key area.

Political parties and democratic politics go hand in hand. Since parties matter, it matters too when elected politicians change party affiliation. This book shows why, when, and to what effect politicians switch parties in pursuit of their goals, as constrained by institutions and in response to their environments.

What do Beppe Grillo, Silvio Berlusconi, Emmanuel Macron (and also Donald Trump) have in common? They are prime examples of the personalization of politics and the decline of political parties. This volume systematically examines these two prominent developments in contemporary democratic politics and the relationship between them. It presents a cross-national comparative comparison that covers around 50 years in 26 democracies through the use of more than 20 indicators. It offers the most comprehensive comparative cross-national estimation of the variance in the levels and patterns of party change and political personalization among countries to date, using existing works as well injecting fresh cross-national comparative data. In the case of party change, it offers an analysis that extends beyond the dichotomous debate of party decline versus party adaptation. In the matter of political personalization, the emphasis on variance helps in bridging between the high theoretical expectations and disappointing empirical findings. As for the theoretically sound linkage between the two phenomena, not only is this the first study to comprise a comprehensive cross-national examination, but it also proposes a more nuanced understanding of this relationship. Comparative Politics is a series for researchers, teachers, and students of political science that deals with contemporary government and politics. Global in scope, books in the series are characterised by a stress on comparative analysis and strong methodological rigour. The series is published in association with the European Consortium for Political Research. For more information visit: www.ecprnet.eu. The series is edited by Emilie van Haute, Professor of Political Science, Université libre de Bruxelles; Ferdinand Müller-Rommel, Director of the Center for the Study of Democracy, Leuphana University; and Susan Scarrow, John and Rebecca Moores Professor of Political Science, University of Houston.

In a campaign for state or local office these days, you’re as likely today to hear accusations that an opponent advanced Obamacare or supported Donald Trump as you are to hear about issues affecting the state or local community. This is because American political behavior has become substantially more nationalized. American voters are far more engaged with and knowledgeable about what’s happening in Washington, DC, than in similar messages whether they are in the South, the Northeast, or the Midwest. Gone are the days when all politics was local. With The Increasingly United States, Daniel J. Hopkins explores this trend and its implications for the American political system. The change is significant in part because it works against a key rationale of America’s federalist system, which was built on the assumption that citizens would be more strongly attached to their states and localities. It also has profound implications for how voters are represented. If voters are well informed about state politics, for example, the governor has an incentive to deliver what voters—or at least a pivotal segment of them—want. But if voters are likely to back the same party in gubernatorial as in presidential elections irrespective of the governor’s actions in office, governors may instead come to see their ambitions as tethered more closely to their status in the national party.

This book explores why some members of Congress are more effective than others at navigating the legislative process and what this means for how Congress is organized and what policies it produces. Craig Volden and Alan E. Wiseman develop a new metric of individual legislator effectiveness (the Legislative Effectiveness Score) that will be of interest to scholars, voters, and politicians alike. They use these scores to study party influence in Congress, the successes or failures of women and African Americans in Congress, policy gridlock, and the specific strategies that lawmakers employ to advance their agendas.

This volume provides an in-depth examination of representation and legislative performance in contemporary American politics.

How much autonomy do elected politicians have to shape and reshape the party system on their own, without the direct involvement of voters in elections?
