The ""swing voter"" occupies a cherished place in American political lore. Candidates court swing voters, consultants target them, and pundits speculate constantly on which way they will lean. But nobody has adequately defined them as a group. What exactly is a swing voter? No one really seems to know. T he Swing Voter in American Politics fills this conceptual gap. The book brings political scientists and pollsters together to answer four basic questions: What is a swing voter? How can analysts use survey data to identify swing voters? How do swing voters differ—if at all—from the rest of the electorate? And what role do swing voters play in determining the outcomes of contemporary elections? Drawing on a wide range of sources, including American National Election Studies Data, Gallup polls, Pew Center surveys, and the National Annenberg Election Survey, the contributors track swing voters across six decades and in national and local elections. The result is an unprecedented picture of this key political group, just in time for the 2008 campaigns. Contributors include James E.
