A Wisconsin State Journal article.
Has this been a feature of the GOP primary in other states? I hadn't noticed. Romney seems extremely low key about his religion. I get the impression he's one of the many people who continue the traditional religion within their families, not because any of the particular details of that religion seem especially persuasive, but because a person tends to need a religion, for social and psychological reasons, and the most moderate approach to religion is to adhere to the faith of your parents and grandparents.
