Those kids are not stupid. The look on their faces says it all. They’re bored out of their skulls by the simple-minded lameness of the event. Worse than that, they’re being used to make their father look like something that he isn’t (empathetic, warm-hearted, compassionate, presidential), and they know it. If the staffer made a mistake, it was in not pointing this out.
It’s not just being bored. It’s contempt. That’s the look on their faces. Contempt is the defining characteristic of the whole Obama family. Contempt for this party, contempt for this father, contempt for the law, contempt for the entire country.
