Unfortunately, the symbolism of Christie’s weight problem goes way past the issue of obesity itself. It is just a too- perfect symbol of our country at the moment, with appetites out of control and discipline near zilch. And it’s not just symbolism. We don’t yet know much about Chris Christie. He certainly makes all the right noises about fiscal discipline and seems to have done well so far as governor of New Jersey. Perhaps Christie is the one to help us get our national appetites under control. But it would help if he got his own under control first.
