AbstractPast research has shown that elected officials are generally responsive to the public's attitudes on policy, particularly in domains such as morality policy. But will this responsiveness survive an externally imposed, non-incremental policy “shock”? The U.S. Supreme Court's decision in Roe v. Wade represents such a shock regarding abortion policy. We examine the responsiveness of state lawmakers to mass abortion attitudes in the post-Roe period through a longitudinal analysis of state abortion policies. We find that the connection between mass abortion attitudes and abortion policies has grown stronger over time, and that mass preferences have become the primary determinant of such policies. Mass abortion attitudes are now a stronger predictor of abortion policies than elite abortion attitudes, and certain elite abortion attitudes that once moderated the link between mass abortion attitudes and policy no longer do so. These findings suggest that lawmakers will attempt to respond to public preferences about contentious morality policies despite the imposition of an external policy constraint.
