Description:
Do partisans sort? If so, why? I address both questions in this paper by developing the Migration-Assimilation-Polarization (MAP) theory of partisan sorting which is tested using Hurricane Katrina migration to Houston, Texas as a natural experiment. According to the MAP Theory, conservative flight induced by changes in diversity provides a mechanism for partisan sorting which can at least partially account for trends in geographic polarization. Using a variety of empirical tools including synthetic controls, I demonstrate that Hurricane Katrina migration led to increases in conservative white flight and geographic polarization between Houston and surrounding counties
