Atheists can expect discrimination when running for office. We know less about political appraisal of other types of nonreligious candidates or how the influence of nonreligion compares to other factors. Using a conjoint experiment, I examine how the impact of nonreligion on vote choice depends on (1) the label describing nonreligion; (2) the electoral scenario in which voters face the candidate; and (3) voters' partisanship and religiosity. I find that atheists and nonbelievers are at a substantial disadvantage but secular candidates suffer a smaller penalty. While nonreligion reduces political support, it is not the most important influence, plays a smaller role in lower than in higher level elections, and is generally not a factor for Democratic and nonreligious voters. In contrast, it is a major liability for Republican, Independent, and religious voters, especially when Republicans vote in nominating contests and when they face atheists or nonbelievers as opposed to secular candidates.
