'In The Collaborative Congress, Alison Craig has produced the best of what congressional scholarship has to offer in understanding how Congress does its job. Using an original and innovative measure of cooperation across members, Craig demonstrates that, despite high levels of party polarization, members of Congress work together across the political aisle on a wide range of issues and achieve surprising levels of success. This sophisticated and engaging book will appeal to students, scholars, and political observers alike.' Wendy Schiller, Brown University
