Santorum started off small government conservative and then over time, he melded into Rinodom and became a “compassionate conservative” interested in “social justice.” Social justice is just a tricky way of saying socialism.
He stayed socially conservative but when you turn over all aspects of human life to control by the Feds, your faith and morals are banned from all your life in public.
You must be listening to some other Santorum. I heard him answer a question on teaching Creationism by saying the decision should be left locally to schools and parents and kept away rom the Fedgov.
