This volume of essays brings together a group of leading political scientists, legal scholars and political theorists to describe and analyze the body of constitutional law and practice within and upon democratic institutions, in particular examining how constitutional law shapes electoral democracy. Constitutional law and practice is complex and varied and so this volume takes a thematic and regional approach: it selects a range of key theoretical questions related to democratic constitutional design, and offers a range of chapters featuring a diverse range of voices, as well as a blend of theory, qualitative studies, and quantitative methods. Readers will gain a multi-faceted understanding of a phenomenon of growing importance and it will be useful to students of comparative constitutionalism, who will gain a rich array of empirical evidence to stimulate further work.
