What Americans Know about Politics and Why It Matters. Yale University Press, 1997.

This book is widely considered to be the most comprehensive analysis ever written about the American public’s factual knowledge of politics. Drawing on extensive survey data, including much that is original, two experts in public opinion and political behavior find that many citizens are remarkably informed about the details of politics, while equally large numbers are nearly ignorant of political facts. And despite dramatic changes in American society and politics, citizens appear no more or less informed today than half a century ago.
