Reconsidering partisanship as a constraint on the persuasive effects of debates

This study tests persuasive effects of 30 debate performances drawn from samples (n = 5780) of 22 states over four election cycles (2004–2016). We test partisanship of the candidate, type of debate (presidential or vice-presidential), gender of the candidate, whether it was the first debate of the cycle, and whether it was a town-hall debate as possible moderators. Results reveal that viewers are likely to perceive their inparty candidate more favorably after viewing a debate, particularly for vice-presidential candidates, Democratic candidates, and female candidates. Debate viewing did not consistently influence evaluations of the outparty candidate. We conclude that debates can persuade and argue for a reconceptualization of partisan-motivated reasoning as a constraint on political persuasion.
