Scholars have identified a variety of mechanisms through which religion could impact vote choice in the United States. Researchers have long recognized that, like other social identities, religion is an important factor in the development of party identification. In the United States, evangelical Protestants and highly committed members of other religious traditions tend to favor the Republican Party, while seculars and low-commitment members of other religious traditions tend to favor the Democratic Party. Religion also impacts views on a variety of issues, including abortion, social welfare policy, and foreign affairs. Under the right circumstances, religious voters may incorporate these policy positions into their vote choice. Finally, a growing body of research recognizes that voters use a candidate's religious views as a heuristic to infer partisanship, ideology, competence, trustworthiness, and a variety of other traits. Given these numerous paths of influence, it is no surprise that researchers regularly find that religion is an important factor in electoral choice.Researchers have also identified a variety of ways in which religion can impact turnout, thereby creating a second means for religion to influence American elections. Religion helps in the development of social networks and civic skills, thus reducing the costs of political participation. Religion can also be a factor in the development of sociopsychological traits such as threat, thereby facilitating mobilization. By understanding the capacity of religion to impact both turnout and electoral choice, scholars can better understand the myriad ways in which religion influences elections in the United States.
