Political and socioeconomic indicators of state restrictiveness toward abortion.

We compare the relative impacts of political and socioeconomic factors on state restrictiveness toward abortion during the pre. Roe, pre-Webster and post-Webster time frames. This analysis tests the value of cycle theory, where shifting epochs dominated by liberalism and conservatism enhance the role of political variables in shaping policy formation. It also tests the explanatory value of public opinion theory which holds that bimodal issues which cut across party lines accentuate the role of socioeconomic variables in shaping issue evolution. The results of this analysis lend support to cycle theory and public opinion theory, although public opinion theory receives stronger support. When socioeconomic independent variables are regressed against our dichotomous measures of state restrictiveness toward abortion, they explain more variance than political independent variables. Political variables were more important in the conservative era (1989) than in the liberal era (1972).
