The Determinants of State Legislator Support for Restrictive Voter ID Laws

We examine state legislator behavior on restrictive voter identification (ID) bills from 2005 to 2013. Partisan polarization of state lawmakers on voter ID laws is well known, but we know very little with respect to other determinants driving this political division. A major shortcoming of extant research evaluating the passage of voter ID bills stems from using the state legislature as the unit of analysis. We depart from existing scholarship by using the state legislator as our unit of analysis, and we cover the entirety of the period when restrictive voter ID laws became a frequent agenda item in state legislatures. Beyond the obviously significant effect of party affiliation, we find a notable relationship between the racial composition of a member’s district, region, and electoral competition and the likelihood that a state lawmaker supports a voter ID bill. Democratic lawmakers representing substantial black district populations are more opposed to restrictive voter ID laws, whereas Republican legislators with substantial black district populations are more supportive. We also find Southern lawmakers (particularly Democrats) are more opposed to restrictive voter ID legislation. In particular, we find black legislators in the South are the least supportive of restrictive voter ID bills, which is likely tied to the historical context associated with state laws restricting electoral participation. Finally, in those state legislatures where electoral competition is not intense, polarization over voter ID laws is less stark, which likely reflects the expectation that the reform will have little bearing on the outcome of state legislative contests. 1Appalachian State University, Boone, NC, USA 2Texas Tech University, Lubbock, TX, USA 3University of Florida, Gainesville, FL, USA Corresponding Author: Seth C.
