Subnational policies and migration in the USA: post-national citizenship or sovereignty?

Abstract

This paper aims to: (i) investigate whether Republican legislatures were more inclined than Democratic ones to uphold laws of national sovereignty and whether Democratic legislatures were more likely than Republican ones to prioritise bills linked to the post-national perspective; (ii) assess the US migration laws by considering how state-level legal systems affect migrants’ lives. Using data from the National Conference of State Legislatures and Legiscan and techniques like clustering, statistical, and geospatial analysis, we found that bills sponsored by the Democratic Party are indeed more likely to belong to the post-national category than bills by the Republican Party.
