This work addresses the development of congressional practices and institutions and ties the changes to key political and economic events. In connecting political and economic events with changes in Congress, the authors examine the political economy of the history of Congress. They draw upon history to offer insights about contemporary issues such as party polarization, filibuster reform, direct election of politicians, intercameral bargaining, and the role of committees in the political process. Through this approach the authors help us to understand how politics and economics interact to affect Congress.
