Victimhood is core to white Evangelical Christian culture in the US - they see themselves as besieged by the forces of Satan in a fallen world. While they do have disproportionate control of the levers of power, they have long felt (correctly) that they hold little sway over broader culture in the country. Their beliefs and lifestyle are not respected by most of the secular, professional class, or by those who produce most of our cultural products (Hollywood, the music industry, etc). They lost the “culture war” long ago, and they just grow more and more bitter about it as time goes on. This is where MAGA came from.
