When it comes to passing actual legislation, putting it forward and getting it all the way through the process, it can be difficult to measure exactly which legislators are effective. Not to mention which types of legislators tend to be more effective, moderates or extremists? And does majority-party membership increase effectives? In an innovative new paper, “Effective Lawmaking Across Congressional Eras”, University of Pittsburgh professor of political science Max Goplerud proposes a new measure of legislative effectiveness that may help us to answer some of these complex questions.
