Over on his personal blog, NOM's Thomas Peters discusses the catholic case for Rick in 2012:

Most people who have heard of Rick Santorum’s political history and reputation have already made up their minds about him.

My argument is, however, that both Catholics who think they know Santorum well and people whose impression of Santorum has been only (mis)formed by the mainstream media don’t know the real Rick.

... I want to talk about Santorum as a “complete” Catholic candidate – one who is extremely strong on the foundational life and marriage issues, but who also advocates for other worthy causes that too-often have been taken over by liberal and progressive ideologies and politicians (all while not actually helping alleviate the underlying problems).
