Issue Evolution, Political Parties, and the Culture Wars

Abstract

Using the issue evolution framework, our research examines partisan polarization on several culture war issues, including pornography, environment, gun control, and gay civil rights. We look for evidence of partisan polarization among political elites and citizens, as well as examine top-down versus bottom-up paths of influence among Republicans and Democrats. Data from the General Social Survey and congressional rollcall votes between 1970-1999 are analyzed. Our results suggest that although partisan elites have become increasingly polarized on culture war issues, mass partisans have not followed suit across all issues. Only on environmental and gun control issues do we find significant evidence of issue evolution, including a linkage between elite and mass opinion. We conclude that culture war issues may not be as prone to issue evolution as previous research has indicated, in part because these issues are not all equally salient to the mass public.
