Problem? Is It Influential? It is because of Christian nationalism that “President Donald Trump” is a phrase that reflects reality and not reality television. Before Trump, Christian nationalism tended toward the corrupt and inept. It was an odd, impotent curiosity. But the 2016 election changed that. Trump won because of Christian nationalism. The movement is still based on lies and myths, but a Christian nationalist was elected president of the United States, and he was elected because of, not in spite of, his Christian nationalism.
