Candidate and party affective polarization in U.S. presidential elections: The person-negativity bias?

Abstract We investigate the degree of affective polarization in presidential election years toward the two major parties and their nominees. Notwithstanding studies which show that individuating information about an out-group member can generate a person-positivity bias, we demonstrate a person-negativity bias directed at out-party candidates at least for some. We motivate and test two hypotheses: first, we expect more sophisticated partisans to display a greater difference in their feelings towards specific candidates compared to evaluations of the parties themselves; second, we anticipate sophisticated partisans will exhibit a person-negativity bias toward out-party candidates and a person-positivity bias toward in-party candidates. The results accentuate the conditional nature of the person-positivity bias and shed light on how political sophistication is linked to affective polarization.
