I assume that you didn’t intend for your post to look like it was addressed at me?
You were/are correct that the GOP-e and libertarians are at war with conservatives. The GOP-e is at war with conservatives on both fiscal issues and social issues, and libertarians are at war with conservatives pretty much just on social issues.
A truce can be reached with libertarians: Conservatives can say they will no longer support an unending war position, and libertarians can drop their attacks on conservatives over social issues. One for one.
Together, libertarians and conservatives can tell the GOP-e that their war on conservatives has to end, or conservatives will leave.
