Americans learned plenty over the weekend about Cindy Hyde-Smith, Mississippi’s junior U.S. Senator, who is running in a special election to finish the term of retired Sen. Thad Cochran. Hyde-Smith, we learned, had not only attended an all-white “seg academy” during the days of integration but had also chosen, far more recently, to send her daughter to a nearly all-white school that had been founded decades prior as another “seg academy.” Hyde-Smith’s attitudes about race had already caused her trouble on the trail; she had made flippant reference to “a public hanging” while campaigning to represent the state where more black Americans were lynched than in any other, and days passed before she offered even a half-apology.
