Party Affiliation, Partisanship, and Political Beliefs: A Field Experiment
Political partisanship is strongly correlated with attitudes and behavior, but it is unclear from this pattern whether partisan identity has a causal effect on political behavior and attitudes. We report the results of a field experiment designed to investigate the causal effect of party identification. Prior to the February 2008 Connecticut presidential primary, researchers sent a mailing to a random sample of unaffiliated registered voters informing them of the need to register in order to participate in the upcoming primary. Comparing post-treatment survey responses to subjects' baseline survey responses, we find that those informed of the need to register with a party were more likely to affiliate with a party and subsequently showed stronger partisanship. Further, we find that the treatment group also demonstrated greater concordance than the control group between their pre-treatment latent partisanship and their post-treatment reported voting behavior and intentions and evaluations of partisan figures. Thus our treatment, which caused a strengthening of partisan identity, also caused a shift in subjects' candidate preferences and evaluations of salient political figures. This finding is consistent with the claim that partisanship is an active force changing how citizens behave in and perceive the political world.
