A fleeting look crossed Hillary Clinton’s face. A sagging of expression when she stepped out of her car in off-white into the damp of the Trump inaugural. Then she braced as always for the questions that would come flying. A second before the figurative veil fell there it was, a weary pain damped down quickly in the face of the public. She is not the easiest person to like, a nerd and a woman in a world where butch populism has devoured ethics, family values and democracy.
