Ideologues without issues: The polarizing consequences of ideological identities

Abstract

The distinction between a person's ideological identity and their issue positions has come more clearly into focus in recent research. Scholars have pointed out a significant difference between identitybased and issue-based ideology in the American electorate. However, the affective and social effects of these separate elements of ideology have not been sufficiently explored. Drawing on a national sample collected by SSI and data from the 2016 ANES, this article finds that the identitybased elements of ideology are capable of driving heightened levels of affective polarization against outgroup ideologues, even at low levels of policy attitude extremity or constraint. These findings demonstrate how Americans can use ideological terms to disparage political opponents without necessarily holding constrained sets of policy attitudes.
