Bernie Sanders made "a Kinsley gaffe—where a politician accidentally reveals a truth he did not intend to admit."

Says Katherine Mangu-Ward at Reason.com. What Sanders said was: "Every other major country on Earth, every one, including some small countries, say that when a mother has a baby, she should stay home with that baby."

Does Mangu-Ward mean that Sanders actually thinks the mother should stay home with the baby or did she mean to say it's actually true that the mother should stay home with the baby? If she only meant the former, didn't she make a Kinsley gaffe?
