Politics & Polls #21: Asymmetric Politics
Political polarization is the worst it’s been since the Civil War, some experts argue. How did we get here? How have America’s ideologies shifted so much in the past four decades? What forces underlie the growing divide between Republicans and Democrats? And how has social media and varying sources of information widened the gap?
In episode 21, professors Julian Zelizer and Sam Wang discuss party polarization with Matt Grossmann and David Hopkins, co-authors of the new book, “Asymmetric Politics: Ideological Republicans and Group Interest Democrats.” Published by Oxford University Press, the book provides a new understanding of contemporary polarization.
Grossmann and Hopkins show how Republicans are more ideological, gaining public support by pledging their loyalty to broad values, while Democrats are more interested in special interest groups, appealing to voters’ group identities and interests through the endorsement of certain policies. The result: two parties that think differently, argue past one another, rely on completely different sources of information and pursue divergent governmental goals.
Grossmann is director of the Institute for Public Policy and Social Research and associate professor of political science at Michigan State University. Grossmann’s research is focused on American politics and policymaking, especially interest group representation and influence, political parties, political networks, campaigns and policy change.
Hopkins is an assistant professor of political science at Boston College. His research and teaching interests include American political parties and elections, the U.S. Congress, voting behavior, public opinion and research methods.
