For the last decade, no issues have more consistently occupied the consciousness of Texas Republican voters than immigration and border security. Evidence provided by multiple polls, considered in the context of politics and policies pursued by a generation of Texas Republican leadership, illustrates how nativism has become a major animating force in Republican politics in the state. While the term “nativism” carries negative connotations, nearly a decade of public polling data illustrate the pervasiveness of such attitudes among Republican voters, even if the term is likely to be hotly refuted by those whose attitudes and (in the case of public figures) rhetoric and policies make the description demonstrably apt.
