When political commentators talk about polarization, they often mean a partisan ideological divide: the left vs the right, republicans vs democrats, progressives vs conservatives. But what if there is a different dichotomy driving our political disagreements that is orthogonal to ideological differences? That’s what University of Miami political scientist Joseph Uscinski argues in a recent paper, “American Politics in Two Dimensions: Partisan and Ideological Identities versus Anti-Establishment Orientations. Using two national surveys from 2019 and 2020, he shows that anti-establishment and anti-elite sentiments may be more of a driving force in our politics than partisan ideology.
