Winner of the 2022 Gladys M. Kammerer Award presented by the American Political Science Association to honor the best book published during the previous calendar year in the field of U.S. national policy.

Reviewed in PSQ, Perspectives on Politics, and New Political Science.

“To know who governs, we must know who controls the governing agenda. In this innovative book, four top political scientists show that the congressional agenda is disproportionately shaped by economic elites and the politicians most friendly to and funded by them. Combining sophisticated quantitative analysis and compelling case studies, Hijacking the Agenda sets a new standard for research on inequality and American democracy—and sounds a loud warning that all scholars and citizens should hear.”

—JACOB HACKER, Stanley Resor Professor of Political Science, Yale University
