Numerous studies have examined the roll call voting behavior of women in Congress. Much of this scholarship has focused on whether female legislators tend to be more liberal than their male colleagues. However, most of this research has examined whether gender differences exist within a specific legislative chamber. This paper seeks to build on this past research by exploring whether the relationship between the descriptive and substantive representation of women is contingent upon the institutional context in which female legislators serve. Using Common Space Scores which estimate the roll call voting behavior of U.S. Senators and U.S. House members on a scale that allows for comparisons across each chamber this study analyzes the voting records of Female Senators, Male Senators, Female House Members and Male House Members in the 109th-111th Congresses. The results show that in the contemporary Congress, gender exerts minimal influence on how legislators cast their votes with the exception of female Republican Senators who are noticeably more liberal than Republicans in both the House and Senate.
