Abstract
There is little doubt that increasing polarization over the last decade has transformed the American political landscape. In The Other Divide, Yanna Krupnikov and John Barry Ryan challenge the nature and extent of that polarization. They find that more than party, Americans are divided by involvement in politics. On one side is a group of Americans who are deeply involved in politics and very expressive about their political views; on the other side is a group much less involved in day-to-day political outcomes. While scholars and journalists have assumed that those who are most vocal about their political views are representative of America at large, they are in fact a relatively small group whose voices are amplified by the media. By considering the political differences between the deeply involved and the rest of the American public, Krupnikov and Ryan present a broader picture of the American electorate than the one that often appears in the news.
