Congressional Reform and Party Discipline: The Effects of Changes in the Seniority System on Party Loyalty in the US House of Representatives

Abstract

The US House of Representatives underwent a series of reforms in the 1970s which, on paper, changed the institution in fundamental ways. Often, however, institutional inertia is able to transform important ‘paper’ changes into barely discernible actual changes. Have the reforms really led to alterations in the way Congress operates and the policies it produces? To provide a partial answer to this question, we single out one of the reforms – a change in the application of the seniority system in the selection of committee chairmen – and analyse it with an eye towards one hypothesized effect – alterations in the level of party support among key representatives. But by restricting our study in this manner, we are able to provide specific empirical facts which should be of considerable assistance in the important task of formulating more generalized conclusions about the ability of legislative reform to produce real change in the governing process.
