National Policies, Agendas, and Polarization in American State Legislatures: 2011 to 2014

Abstract

Why are some states polarized and others not? This article argues that state legislators are provided with more information by lobbyists and the media about national policies, or state-level bills that are prominent in the national political discourse. Compared with state-specific issues, this additional information encourages legislators to vote along party lines to secure reelection or prepare for a run for higher office. It identifies national policies using lobbying registrations in state legislatures and Congress to show there is more party difference on roll-call votes on national policies in 25 states over 2011 to 2014. It also argues that the notoriety of national issues may encourage party leaders to put these bills on the agenda to build their party brand, or for individual legislators to raise their profiles. It finds that states with more national agendas have more polarized sessions.
