Yeah seems likely. I don't want to get too much into the details but I know a lot of "George W." type christians; converted under hardship, their core belief is likely sincere but they aren't necessarily invested in nuanced understanding of its role in a broader public life. They look to their church leadership for that, locally but also in the vast mainstream of evangelical bookstores, podcasts, radio stations.

A domain that is becoming more narrow in its understanding of scripture and extreme about applying it. Look at someone like Beth Moore, a highly prominent figure in this world and by no means a liberal or progressive, viciously chased out for openly holding a view on marriage¹ that would have been easily accepted by evangelicals even a generation ago, and that many probably do privately hold still.

So yes it's entirely possible our evangelical acquaintances have little overlap. But still, these are mainstream views right now and growing more so. You can find dominionist books by prominent christian authors in the window displays of christian bookstores. It may not be the majority of evangelicals, but it is a significant portion and making it the majority is explicitly one of their goals. Dismissing this movement as fringe is irresponsible imo.

¹: The view is "egalitarianism" the idea that both genders have equal privileges and responsibilities within marriage. This is not "wokeism" my southern baptist grandparents believed this.
