Considered the "gold standard" of political parties texts, this new, eighteenth edition of Party Politics in America moves its comprehensive and authoritative coverage into the age of deepened partisan conflict, expanded presidential power, and global health threats. Marjorie Randon Hershey builds on the book’s three-pronged coverage of party organization, party in the electorate, and party in government and integrates important developments in racial politics, social media use, and battles over access to the vote. The book uses contemporary examples to bring to life the fascinating story of how parties shape our political system. New to the eighteenth edition: • Fully updated through the 2020 election, including changes in virtually all of the boxed materials, the chapters, and the data presented. • Examines the impact of the Trump presidency on the Republican Party’s supporting coalition and issue positions, changes in party and ideological polarization, and the return to the world of campaign finance of "interested money" from big (and often anonymous) donors. • Explores political attitudes and voter turnout among college-age and other young voters in light of dramatic changes in American politics and the economy. • Expanded online Instructor’s Resources, including author-written test banks, essay questions, relevant websites with correlated sample assignments, the book’s appendix, and links to a collection of course syllabi.
