Here is an Atlantic Wire article about it. I don’t think we have too many tokens of presidential dignity. Even though we don’t have a king, we still have a head of state, a commander-in-chief and a representative of our government to citizens, and a representative of America to non-citizens. And Chait’s article didn’t identify any real problem or excess of presidential dignity. We really don’t have that much.
I would say Stewart shouldn’t call anybody dude on tv unless he’s friends with him. He shouldn’t call a mayor ‘dude,’ or an alderman. He clearly shouldn’t call the president that.
But, I think Stewart clearly has respect for the president. I think it was an accident. It was tiny thing and doesn’t deserve media coverage.
