8Now in its fourth edition, this textbook gives a clear and concise account of the government and politics of democratic states, comprehensively updated with recent developments. It provides an ideal guide for undergraduate students who want to understand how and why democratic systems differ between countries and how they are changing in the modern world. It is written and structured in an easy to follow style, enabling students to gain a thorough understanding of the explanations behind complex ideas and theories. The 'Briefings' and 'Controversies' sections give life to the analyses with illustrations drawn from around the globe, whilst its 'Key Term' entries provide students with a route through the concepts of political science. The fourth edition has been fully revised to reflect recent changes in political attitudes and behaviour, voting, parties, party systems and ideologies. The final chapter addresses the future of democratic states facing with these changes and challenges, by examining democratic crisis, populism and post-democracy.
