There's a significant possibility that 2012 will be the year that America confronts the question of whether a Mormon can be president. It seems like a question with an obvious answer ("I don't know. Can he?"). But surveys in recent years have consistently found that a large minority of voters are set against the idea, and the prejudice may be even more deeply rooted among a Republican primary electorate that is, as my colleague puts it, "struggling to decide which it hates most—being a Mormon or being sensible."
