Although the literature on congressional change has established that political parties in Congress have become increasingly polarized over time, this conclusion is limited to the study of voting behavior. The analysis of another legislative practice, bill cosponsorship, reveals that while the parties in the House have divided, those in the Senate have not. This suggests that (1) the extent of party polarization varies across stages of the legislative process and (2) there are important differences in the personal interactions of legislators in each chamber.
In the dissertation, I make several claims about cosponsorship networks and behavior in the House and Senate. First, I argue that the rigid structure of the House and the routinized behavior it encourages lead members to rely on party loyalty as a behavioral cue. As a result, House members tend to associate with more of their same-party colleagues at the expense of building relationships with their partisan opponents.
Meanwhile, the institutional structure and rules of the Senate force senators to interact and build relationships with their colleagues on both sides of the aisle more regularly than representatives must. As a result, the networks of senators are more diverse than those of representatives. Overall, the dissertation illustrates that using an alternative measure of party polarization produces results different from what the traditional literature suggests.
