I don't know a single Republican that would argue that religious people, leaders or clerics should be banned from participation in public affairs. We ALL encourage it.
However Santorum's own words say he is an advocate for "the church" (read: Institutions) should have a role in the OPERATION of the government.
No, our Founding Fathers put an end to that nonsense over 200 years ago.
Please address that issue.
Santorum does not want a theocracy. He probably meant in the operation of our government the way all people and entities here do, through lobbying.
