Abstract: In this paper, we examine polarization and partisan divergence in the American public on economic issues over the past 70 years. We bring to bear a new dataset that contains over half a million respondents from hundreds of individual polls. This dataset contains the responses to over 150 question series about economic issues. We combine this dataset with a dynamic group-level item response model to measure the ideology of the American public at both the state and national levels between 1946 and 2012. We find that the American public has only become modestly more polarized on economic issues over the past 70 years. However, the two parties are much more clearly sorted on economic issues today than in earlier decades. Moreover, members of the two parties are now further apart than ever before at both the state and federal levels. Our results speak to debates about polarization. They also suggest that partisan divergence in the mass public may have contributed more to elite polarization than scholars have previously thought.
