The Cost of Majority‐Party Bias: Amending Activity under Structured Rules

Abstract

All major legislation in the House necessitates a special rule from the Rules Committee before it can be brought to the chamber floor. These rules often strictly limit floor amendments to bills considered by the House. Scholars of political parties have argued that the House majority party can bias policy output away from the floor median through its usage of restrictive rules. In this article, we argue that in order to secure the passage of restrictive rules, the majority often makes concessions to centrist legislators through the amending process. We examine this theory using a newly collected data set that includes all amendments considered by the Rules Committee during the construction of structured rules in the 109th, 110th, and 111th Congresses (2005–2010). Our results are mixed, but they do suggest that moderate members of the majority party often receive concessions via amendments for their support of the majority party's agenda‐setting regime.
