Bill de Blasio, the mayor of New York City, and Hillary Clinton, made a mistake. They had a skit that involved Hillary asking why it took so long for de Blasio to endorse her, and he invoked a racially charged term, that she defused. The comedic timing could have worked with different “actors” and in a different setting, but it fell flat there, and raised lots of eyebrows. I am bothered by what he did, but not because I think he’s a racist, or that the joke was racist, but because I think he betrayed a trust. The video is here, and Clinton joins the act around 7:45. The attempt at the joke starts at 8:30.
