Nobody should be surprised that evangelical voters are sticking with the GOP.
I’ve been watching evangelical voting behavior since I worked for Paul Weyrich’s Free Congress Foundation in the 1980s, and I’ve come to believe that, in most cases (though certainly not all), white evangelicals get their religion from their politics, not their politics from their religion.
That is, many evangelicals are first and foremost political conservatives drawn to a church (or a pastor) that confirms their worldviews and, in turn, their political views.
They gravitate to evangelical, fundamentalist and Pentecostal churches that are spread across the American landscape, particularly in rural and small-town America, because those churches hold views about the Bible and human behavior that are traditional rather than pragmatic. Not surprisingly, most of those church members are politically conservative, particularly on social/cultural issues but increasingly also on the role of government.
For many white evangelicals, their religious and political views are so strongly intertwined that it is almost impossible to separate them. When their views of religion and morality collide with politics, politics often wins out. That’s why it’s naïve to ask why so many white evangelicals continue to support Donald Trump or Roy Moore.
