Political factors influence judicial decisions. Arguments and input from lawyers and interest groups, the ebb and flow of public opinion, and especially the ideological and behavioral inclinations of the justices all combine to influence the development of constitutional doctrine. Constitutional Law for a Changing America draws on political science as well as legal studies to analyze and excerpt cases.

With meticulous revising and updating throughout, Epstein and Walker streamline material while accounting for recent landmark cases and new scholarship. This seventh edition features two important improvements:

- a completely revamped interior layout and design that clearly delineates between commentary and opinion excerpts while more effectively showcasing photos, justice biographies, and the Aftermath and Global Perspective sidebars.
- the case commentary not only details the case Facts but now includes an Arguments section that details the attorneys arguments for each side, leading to more focused and effective reading of the case.

Cases new to this edition of Rights, Liberties, and Justice include Morse v. Frederick (2007), United States v. Williams (2008), Arizona v. Grant (2009), Safford Unified School District #1 v. Redding (2009), Herring v. United States (2009), Parents Involved in Community Schools v. Seattle School District No. 1 (2007), Meredith v. Jefferson County Board of Education (2007), and Crawford v. Marion County Election Board (2008).
