Congressional Parties and the Mobilization of Leadership PAC Contributions

Abstract

A B S T R A C TTraditionally, observers have characterized leadership political action committees (LPACs) as tools used by political entrepreneurs to build personal coalitions supporting their power and policy goals. We argue that political context -namely, competition for control of the House and the advancement structures created by the parties -shapes the way House members use LPAC contributions to advance their careers. As congressional parties have become more oriented towards attaining majority status since the GOP takeover in 1995, LPAC contributions should have shifted towards helping the party win majority status rather than building individual coalitions. We use rare events logit to estimate the probability of incumbent to candidate contributions in the 1990, 1998 and 2004 election cycles. Our evidence shows that Democratic, but not Republican, LPAC contributions have generally become more party-centred as party margins have tightened.
