I am skeptical that it is easy to get accurate numbers on White Nationalists and their religious beliefs. For example, what you are labeling White Nationalist may include a lot of people who don't have the will to do anything actually racist like expelling every single person of a particular ethnicity from their country regardless of whether they came legally or illegally.
I would guess there are very, very few American Christians, even ones who espouse "White Nationalist" sentiments that would be willing to expell a Mexican who isn't a criminal who they personally know. They will tell you things like, "That one in particular can stay. He's a good boy who dindu nuffin and works hard. What would Jesus want?". They aren't really White Nationalist.
Since I don't really have any numbers or scientific data to work with, let's entertain your idea that there are a lot of White Nationalist Christians without trying to define White Nationalist too rigidly. I think it's because lower class people are on the "schizophrenia spectrum" and anyone who is on this spectrum freely believes in contradictory ideologies and will use mental gymnastics to avoid facing the most obvious problems. Every Christian partakes in an activity which is fundamentally stupid because religion requires critical thinking to be banned from confronting it, so in order to be religious you have to either be stupid all around or you have to wall off a section of your mind which is reserved for stupidity.
The "Schizophrenia spectrum" is something like this:
1. Religious or Superstitious
2. Schizotypal
3. Schizophrenia
