The book, co-written by Perry and Yale sociologist Philip Gorski, lays out a scale of Christian nationalism based on agreement with seven points, including “the federal government should declare the United States a Christian nation,” and “the success of the United States is part of God’s plan.”

Their research shows how, the higher people are on the Christian nationalism scale the more they tend to agree with the statement “we make it too easy to vote.” The same thing happens when people agree with the statements “the best way to stop bad guys with guns is to have good guys with guns,” and “authorities should be able to use any means necessary to keep law and order” and “if national security is at risk, I support torture.”

“Even after accounting for partisanship and political ideology, the more strongly White Americans affirm Christian nationalism, the more likely they were to respond to Trump’s election loss with a view that voting access should be restricted even more,” the book says.
