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.
