There's a difference between being a warrior on issues of religion and the family (what I call social conservatism) vs being a warrior on issues of national identity (what I call cultural conservatism). People who are primarily social conservatives by my definition tend to be less right wing on racial issues than people who primarily cultural conservatives are. Example: George W. Bush.
Trump himself is decidedly the latter. He decided to take up enough social conservative issues like abortion and SCOTUS in order to win both blocs of voters. I expect the GOP to be primarily cultural conservative going forward while throwing enough bones to social conservatives (who won't vote for progressives) to keep them in the fold.
Also, people who prioritize social conservatism over cultural conservatism (in the South at least) are disproportionately located in suburbia, not rural areas. I'm not saying that it's the dominant ideology across suburbia, but these views tend to follow the trends of higher church attendance in more well-off areas.
