This new edition of the bestselling The Logic of American Politics is thoroughly updated and covers the dramatic 2016 election results with a thorough analysis of those results. It arms students with a revised introduction to institutional design that makes concepts such as command, veto, agenda control, voting rules, and delegation easier for students to master and apply, so they clearly see how the American political system was devised and why it works the way it does. Authors Samuel Kernell, Gary C. Jacobson, Thad Kousser, and Lynn Vavreck build students' critical thinking through a simple yet powerful idea: politics is about solving collective action problems.
