Redistricting, responsiveness, and issue attention

We explored the extent to which legislators respond to redistricting- induced demographic shifts in their constituencies. Our analyses focused on the behavior of members of the House of Representatives who served in the terms preceding and following the redistricting that took place in the early 2000s (namely, the 107th and 108th Congresses). We investigated how demographic shifts relate to the content of legislators' subsequent agendas (the legislation that members introduce and cosponsor) and the nature of members' voting patterns (their interest group voting scores). Our results indicate that responsiveness is widespread, but important variation exists in the patterns for agenda activities and roll-call voting.
