Americans regularly rail against so-called "special interests." Yet, many members of society are themselves represented in one form or another by organized groups trying to affect government decisions. Interest Groups in American Politics, Third Edition, is grounded by the role of information in interest group activity, a theme that runs through the book. This concise, thorough text demonstrates that interest groups are involved in the political system at all levels of government--federal, state, and local--and in all aspects of political activity, from election campaigns to agenda setting to lawmaking and policy implementation. Rather than an anomaly or distortion of the political system, interest group activity is a normal and healthy function of a pluralist society and democratic governance. Nonetheless, Nownes warns of the dangers of unwatched interest group activity, especially in the realms of the electoral process and issue advocacy.

This much-anticipated third edition of Nownes's text retains a student-friendly tone. It thoroughly updates the references to interest group research, social media activity, new foreign actors in American politics, and political action committee (PAC) and party connections. Numerous figures and tables throughout the book help students visualize significant trends and information.
