Trump won the nomination because the importance of religion is declining, the religious right will disappear over the next few cycles and be replaced by the nationalist right. The religious right failed in every way and the nationalist right is not handicapped to the same extent by concerns about morality or ethics which will make it more effective in opposing the left than the religious right was.
The argument for trump morally speaking basically was that the left had destroyed all sense of morality and tradition during the cultural revolution of the 1960’s and the right worrying about such things was simply putting it at a disadvantage, therefore the right should adopt the left’s utilitarian approach to politics, I think going forward most republican voters will support this position as it makes sense and allows for a more even contest.
Absolutely this. The GOP's struggle this decade has been all about the vacuum left by the death of the religious right. Is the populist right the next dominant paradigm in the party? Uncertain. If racial polarization continues, and/or progressives win in the Democratic Party, we could see suburban whites come home and complicate the party's economic views. My guess is that social utilitarianism is here to stay in the Republican Party, but we haven't seen the last of "globalism" on the economic side.
