As always, the cruelty is the point:
Christian nationalism has provide little in terms of tangible benefits for the the group from which it draws its support, while seeking to erode the rights and status of almost everyone else. The losers under Christian nationalism will be the targets of White reactionary politics. Again, from Perry:
"Religious, racial, and sexual minorities lose as their very existence (not to mention their cultural and political influence) is publicly demonized and perhaps in some cases curtailed. Working class White Americans (even the Christian ones) exchange the possibility of a better economic future for the false promise that some mythical Christian heritage and values will be preserved."
Second, there are some areas where Trump has delivered, such as on abortion access, that provide guidance to what he will do in a second term. Judges appointed by Trump are primed to present to SCOTUS cases that allow them to push the boundaries of Christian nationalist values. More such judges, more cases, offered to a SCOTUS supermajority that no longer feels the need to find a middle ground on these issues.
Third, Trump’s approach to governance will be more sophisticated in a second term. He has a blueprint for governing that bears the imprint of supporters who are open about the goal of imposing Christian nationalist values. This includes familiar areas such as immigration, and education. Trump lawyers committed to a Christian nationalist agenda will operate in concert with their judicial brethren. The Alabama IVF decision rested on an 1872 law. Trump allies plan to leverage the 1873 Comstock Act to prevent the distribution of abortion medication. The1872 Alabama law was about civil lawsuits for wrongful death of children, and the Comstock Act is about the shipping of obscene materials. But sufficiently motivated Christian nationalist lawyers are happy to explain how each law prohibits the use of technologies that would not be invented for a century.
