In states including North Dakota, Mississippi, Alabama and West Virginia, half or nearly half of residents support the view that Christians should dominate all areas of American society, including its laws, according to a new survey about the influence of Christian nationalism by the Public Religion Research Institute, based on interviews with more than 22,000 people.

The nonprofit’s latest research mapped support across all 50 states for a set of religious beliefs that used to belong to the fringes of Christianity in the United States.

Nationally, about three in ten Americans believe, or at least sympathize with, ideas that claim the U.S. is a Christian nation and that the country’s laws should draw from Christian values.
