The causes of union political involvement: A longitudinal analysis

This study examines the political involvement of unions over the 1978, 1980, and 1982 congressional elections. An empirical model focusing on the campaign contributions made by unions and the number of registered lobbyists employed by unions is elaborated and tested. The findings suggest that unions’ political activities are systematically undertaken and that they have increased dramatically over the past three elections. Specific characteristics of unions, such as membership size and dependence on governmental regulations, directly affect the political involvement of unions. Further, given the current economic and political climate, it is likely that this political action will continue to increase. The authors are grateful to Jack Fiorito, Cynthia Gramm, David Lewin, Frank Lichtenberg, two anonymous referees, and the participants in the labor seminars at the University of Illinois and the University of Iowa for helpful comments on an earlier version of this study.
