In the Eighteenth Edition, co-author Hahrie Han introduces an innovative new case-study framework that helps students see their own significance in the political system. Each chapter opens with a real-life example of a person whose engagement with government provides insights on a key question: If, when, and how do people matter in the American political system? The case is then woven through the chapter to introduce key concepts, and help students understand the significance of how the American political system affects our lives. Additional features and pedagogy in the Norton Illumine Ebook help students make sense of data—a long-standing hallmark of the book—and see how they can use evidence to answer questions about American government.
