**Sample size**: 4027
**Field period**: 08/31/2019-1/21/2020
**Abstract**
This experiment examined the effect of priming partisan identity on support for electoral fairness.
**Hypotheses**
Priming partisan identity increases support for co-partisans who undermine electoral fairness.
**Experimental Manipulations**
Respondents were randomly assigned to a task designed to prime partisanship and a placebo task.
**Outcomes**
Probability of supporting the electoral fairness-undermining candidate in a candidate choice scenario.
**Summary of Results**
The treatment effect on partisan identity was smaller than in pilot studies and did not meet conventional levels of statistical significance (covariate-adjusted B = 0.042, s.e. = 0.027; unadjusted B = -0.024, s.e. = 0.061). The estimated effect on support for undemocratic co-partisans was close to zero (covariate-adjusted B = -0.007, s.e. 0.008; unadjusted B = -0.004, s.e. = 0.014). Estimates calculated as described in the pre-analysis plan: https://osf.io/gw493/
