Judge Napolitano on FOX news pulled up this interview of Rick Santorum from 2005 saying this:
He’s a “winner” in Iowa’s Republican caucusing, but he’s a big government guy who pretty much outright states he opposes the beliefs of the basic freedoms the US is all about – not having government intrusion in the lives of citizens. In no way does what he says here jive with conserving the principles of the US constitution – a compact between the citizen and the state – that creates an explicitly limited government.
