He specialises in American foreign policy, US environmental policy, and the values and traditions that shape political institutions and policy outcomes in Washington. His present work explores how US national parks connect environmentalism with foreign policy, shaping America's global environmental identity. His previous work, Charles de Gaulle, the International System, and the Existential Difference (Routledge, 2017), examined how ideas and national identity shaped Franco-American relations during the Cold War.Daniel Stevens is Professor of Politics at the University of Exeter. His research on political behaviour and political communication mostly focuses on the United States and Great Britain. He is the author of the books Truth in Advertising: Lies in Political Advertising and How They Affect the Electorate (2018), with Barbara Allen, Everyday Security Threats: Perceptions, Experiences and Consequences (2017), with Nick Vaughan-Williams, and co-editor, with Susan Banducci, Laszlo Horvath and Ekaterina Kolpinskaya of Media and the British General Elections of 2015-19 (2025).Andrew Wroe is a senior lecturer in American politics at the University of Kent in the UK. He was previously chair of the UK Political Studies Association American Politics Group. His research interests include political trust, polarization, immigration policy, and the Republican party. He has authored, co-authored and edited many articles and books on American politics, including: The Republican Party and Immigration Politics: From Proposition 187 to George W. Bush (Palgrave Macmillan, 2008); The Ordinary Presidency of Donald J. Trump, with Jon Herbert and Trevor McCrisken (Palgrave Macmillan, 2019); and Developments in American Politics 10, with Gillian Peele, Jon Herbert and Raymond La Raja (Palgrave Macmillan 2026).

This textbook does an excellent job of combining constitutional foundations with theory and history and linking these to contemporary political actors and debates. It is extremely comprehensive and highly topical. Concepts and ideas are clearly explained, with great use of case studies and examples to aid student understanding. Detailed resources throughout further support learning beyond the classroom. For the next few years, this will be the standard textbook for university modules on US politics.
