Factions in Committees: The U.S. House of Representatives

Abstract
This study undertakes a major reanalysis of the decision-making processes in eight committees of the U.S. House of Representatives–Agriculture, Education and Labor, Interior and Insular Affairs, International Relations, Interstate and Foreign Commerce, Post Office and Civil Service, Public Works and Ways and Means. While past studies have relied mainly on interviews, this study uses a data base composed of recorded committee roll-call votes. The analysis consists of a Q-component analysis to determine voting blocs or factions; an R-component analysis to discover issue dimensions; and step-wise regression and correlation utilizing demographic, political and electoral characteristics to define the nature of the voting blocs. The results are then compared with previous analyses of the same eight committees to determine what changes, if any, have occurred since the committees were last analyzed. The findings suggest that partisanship and ideology have become stronger influences on committee decision making than previously noted.
