This brief text presents, in a separate book, the revised and updated theoretical chapters (Parts I and II) from the best-selling Comparative Politics Today, Seventh Edition. In this new edition, the rich theoretical framework pioneered by Gabriel Almond and G. Bingham Powell has been streamlined by new co-editors Kaare Strom and Russell Dalton and features a shift toward exploring the purpose of government. Retained and enriched, the three-part analytic framework examining system, process, and policy offers readers a coherent and accessible means to exploring how different political systems are formed, maintained, and changed.
