Republican presidential candidate Mitt Romney says his faith’s prohibitions on premarital sex, alcohol consumption, and caffeine use have had a “liberating” effect on his life rather than an inhibiting one. In a companion interview, his wife reveals his vice: chocolate milk. And when he needs to kickstart his day, he resorts to hot chocolate, she says. “My view is that the commandments of God ... are not so much restricting as liberating,” Mitt Romney said during an interview with Parade magazine.
