Last night on the Daily Show, Al Madrigal travelled to Tucson, AZ, where the local high schools have just been banned from teaching Mexican-American Studies by the state. He sat down with the head of the school board who spearheaded the ban, and it’s the quintessential Daily Show interview: a master class in setting someone up and then getting out of their way while they obliviously tear apart their own argument. By the time he has the guy trying to teach a black kid about slavery without him becoming resentful towards white people, it’s a total trainwreck in the best possible sense.
