If there is to be a unified GOP beyond 2016 — post-Trump — the party must re-work its stances on the issues, from immigration to taxes to foreign policy to be more in tune with the country at large.

Yes, I agree, but the re-working should not mean significant loss of identity to conform to a position that happens to be popular with vote pandering Democrats.

If it were me, Id drop anything related to religion and focus on conservative fiscal values, accountability and defense. If some Republicans want to form a separate Christian party, then let them, as in the end they will vote Republican because the new GOP would at least not be directly antagonistic to them.
