They've done a good job of it so far - leaving a weak and unattractive party for many true conservatives.
I think your wrong as I have stated, Rand Paul is as socially conservative as they come. He is against abortion with no exceptions and supports a Life at Conception Act, he’s a christian conservative but he just thinks you dont want to look for the Feds for solutions, look to your own church and state.
He is also for a strong national defense - as authorized in the constitution but he rejects overseas spending. Bring that money home and spend it here or give it back through tax cuts. That doesn’t mean weak defense. Rand has said he supports missile defense for cities and states and may support building one rather than worrying about other countries security.
