In my raised-in-the-backwoods, many-generations-a-hick experience, Christofascism is almost exclusively concentrated amongst upper middle class and wealthy folks. Lots of poor folks go in for white nationalism, sans Jesus. Few are on board with a church telling them what to do.
Not that the latter isn't a problem, but it's a different problem.
Also: I know lots of poor rural folks who aren't interested in white nationalism at all, and think just as poorly of the Trumpsters/friends of David Duke in their midst as the rest of us do.
We're in a pervasively raciat society, so it has an effect damn near everywhere. But for fash in general the base is upper-middle class and above. Growing up, the comfortably well-off were far more zealously racist than almost any poor person I met.
The church demands an appearance of piety that a lot of rednecks find fake/hypocritical. Democrats often find similar problems getting toe-holds with this group, though, because of the "pointy headed liberalism" and paternalism. No one wants to support people who look down their noses at them.
