A foolish consistency is the hobgoblin of little minds. New Jersey Gov. Chris Christie made precisely that mistake.

I speak of Kaci Hickox, the nurse Christie forced into quarantine when she returned from Ebola relief work in West Africa last week, even though Hickox was not sick. Christie, eager to score political points with the Republicans’ law-and-order crowd before this week’s elections, had Hickox confined to a field tent adjacent to a hospital in Newark. Hickox had no shower, television, or reading materials—and unfortunately for Christie, no fever, vomiting, or any other symptoms of Ebola, either. Then again, why would she? Blood tests done here in the United States found no virus in her body.
