They are-generically speaking of course-more Christian (Catholic) and family oriented whilst being less urban than other populations. That is a recipe for a conservative if there ever was one.
They also may identify as American first rather than, say, Mexican if they are not first generation immigrants. This leads to views that often align with white Republicans far more often than you’d think, especially when you factor in the jobs they have fair access to like the oil/construction/trucking/agriculture industries and the people they’re mingling with there. As for the other minorities thing...I ain’t touching that with a ten-foot cane pole.
