Polarization in Black and White

Abstract

Abstract While the alignment of partisan and ideological identities—sorting—serves as a primary explanation for the rise in affective polarization, we theorize that this connection does not hold for all Americans, especially racial subgroups with unique political experiences. Using both cross-sectional and panel data, we find that even though Whites have sorted, and differences between the South and elsewhere have diminished over time, Black Americans have not sorted since 1972. However, affective polarization is just as high among Blacks as it is Whites. Thus, sorting does not appear to explain Black affective polarization. Multivariate models provide additional evidence that sorting does not adequately explain affective polarization among Blacks. Instead, we find that group norms and group consciousness (e.g., linked fate) better account for affective polarization among Black Americans. These findings provide important nuance to the sorting thesis and shed light on the relationship between sorting and affective polarization.
