Nearly one in five evangelicals and Catholics are undecided about which presidential candidate to support, according to a survey released Monday.
In addition, fewer Protestants and Catholics identify themselves as Republicans than did four years ago, according to Calvin College’s Henry Institute for the Study of Christianity and Politics in Grand Rapids, Mich., which commissioned the survey.
Protestants, as well as Latino Catholics and religiously unaffiliated Americans, could be the crucial “swing vote in the electorate,” said Kevin den Dulk, a political scientist at Grand Valley State University in Allendale, Mich.
