Replication Data for: Senate Responsiveness in an Era of Inequality: The Case of the U.S. Senate"

To what extent do members of Congress respond unequally to people in different economic situations? How does partisan control of the agenda change the way in which Senators respond to the poor? Using data from the 2004 National Annenberg Election Survey, and multiple roll call votes, I examine Senate responsiveness for the 107th through 111th Congresses. The results show consistent responsiveness toward upper income constituents. Moreover, Republicans are more responsive than Democrats to middle-income constituents in the 109th Congress, and a case study of the 107th Senate reveals that responsiveness toward the wealthy increases once Democrats take control of the chamber.

美国国会议员对不同经济状况群体的回应存在多大程度的不均等性？党派对议事日程的掌控会如何改变参议员对贫困群体的回应模式？本研究依托2004年全国安嫩伯格选举调查（National Annenberg Election Survey）数据与多份国会唱名表决记录，对第107届至第111届美国国会的参议院回应性展开考察。研究结果显示，参议员对高收入选区选民始终保持稳定的回应性。此外，在第109届国会中，共和党议员对中等收入选区选民的回应性高于民主党议员；对第107届参议院的个案研究进一步表明，一旦民主党掌控参议院，议员对富裕群体的回应性便会提升。
