Redistricting received substantial attention in the popular media in 2011, as states redrew state legislative and congressional district boundaries. Many reformers continue to argue for a de-politicization of the redistricting process, claiming that partisan redistricting is responsible for declining electoral competition and increasing legislative polarization. Our analysis of evidence from state legislatures during the last decade suggests that the effects of partisan redistricting on competition and polarization are small, considerably more nuanced than reformers would suggest, and overwhelmed by other aspects of the political environment.

How do term limits affect the electoral changes caused by state legislative redistricting? To answer this question, we compare the success of majority parties in the redistricting process in legislatures with and without term limits. We hypothesize that majority parties use the districts of term-limited members to redistribute supporters from safe districts to more competitive ones. We find that, indeed, the majority party changes district lines more in districts with term-limited legislators. Furthermore, the majority party is more strategic in reallocating voters for partisan gain in termlimited districts. Thus, our findings suggest that term limits make the redistricting process more partisan and that a reform intended to remove incumbents from the legislature actually strengthens the majority party.

Roll-call data have become a staple of contemporary scholarship on legislative behavior. Recent methodological innovations in the analysis of roll-call data have produced a number of important theoretical insights, such as understanding the structure of congressional decisionmaking and the role of parties and ideology in Congress. Many of the methodological innovations and theoretical questions sparked by congressional scholarship have been difficult to test at the state level because of the lack of comprehensive data on various forms of state legislative behavior, including roll-call voting. The Representation in America's Legislatures project rectifies that problem through collection of comprehensive state legislative roll-call votes across all 99 state legislative chambers for the 1999–2000 and 2003–04 legislative sessions. In this article, we describe the data available through this project as well as our data acquisition procedures, including Stata and Perl programming and OCR of paper documents, with suggestions about how to use these methods to collect a wide range of state-level data.

State legislators routinely run for the state Senate after having served in the state House; however, this rarely occurs in the other order. Do members simply look to move up based on the conventional view of the political ambition ladder? Alternatively, do institutional reasons exist that make the Senate the preferred chamber? I examine the differences between the state legislative chambers and discuss institutional reasons why members may prefer the Senate to the House. Overall, I find chamber size is an important intra-institutional variable in explaining this variation along with the professionalism of the legislatures and term limits.
