Politics is downstream of Culture, and Culture is downstream of Metaphysics (or Spirituality). While treating symptoms may be helpful, it is no substitute for treating the underlying illness.
The rise of emotional Christianity over intellectual Christianity is what has given us a non-Christian leadership caste even as there are plenty of Christians. It began with Methodism, and has progressed to rock concert churches with ultra simple repetitive hymns -- the type of churches designed to scare away Vulcans.
Then the Mainline Protestant denominations dumbed themselves down and lowered their standards in order to be Relevant. I saw this happening in the Episcopal Church as a kid back in the early 70s.
If we don't want to be ruled by nihilists, we need a truly Christian denomination that can appeal to the intellectual classes.
