The New York Times thinks it may have figured out why the Catholic vote is going for Hillary Clinton in the Democratic primaries: “Mrs. Clinton owes some of her success to the nuns who were once a potent presence in American Catholicism.” Well, now, that’s an idea. I admit there’s some resemblance between Mrs. Clinton and the popular image of the stern, knuckle-rapping nun, but those nuns all disappeared around 1965, and, anyway, who would want to vote for one?
