Education Secretary Betsy DeVos, whose life’s work is to take funds out of public education and give it to private religious charter schools, struggled to explain her philosophy on 60 Minutes last night. It was a funny journey into the exciting new mode of conservative thinking that everyone’s talking about. When the desire to do something isn’t backed by a coherent ideology (or one you dare to explain), describing it becomes a deer-in-headlights nightmare of fixed smiles and random thoughts springing into life and evaporating almost before an interviewer can pop them with simple, unchallenging questions.
