Abstract
This study investigates the impact congressional roll call votes on the North American Free Trade Agreement (NAFTA) had on corporate and labor political action committee (PAC) contributions during the 1994 House elections. The results show that corporate PACs gave more money to incumbents who voted in favor of NAFTA and that labor PACs contributed less money to pro-NAFTA incumbents, including Democrats in competitive races. The findings mark a departure from the existing literature, which indicates that corporations and unions rarely place an emphasis on particular roll call votes when providing their campaign money to candidates.
