Drinking the Tea: The Tea Party Movement and Legislative Agendas in the U.S. Senate

This article empirically investigates the impact of the Tea Party movement in the U.S. Congress by examining senatorial legislative agendas, including bill and resolution introductions and cosponsorships. Specifically, we test how senators responded to the Tea Party movement by increasing their attention to specific Tea Party issues. Our analysis accounts for state-level and electoral factors, including the level of grassroots Tea Party activity in a senator’s home state and the presence of a Tea Party primary challenger. Our findings indicate that the Tea Party led Republican senators to focus more on economically conservative issues in their legislative agendas, and that this impacted the Republican Conference as a whole. Our study of the Tea Party movement in the Senate highlights how national forces can shape legislative activity in Congress.
