I disagree with this conclusion: It's too easy to blame someone else, a way of maintaining our own sense of innocence. Things happen in a democracy when voters insist on it. I'm willing to bet that nobody reading this will do anything about this problem. The great majority will not even vote for their local politicians and can't even name them besides governor and mayor (try it: name your state legislators and judges). EDIT: How many reading this would serve if called for jury or grand jury duty?
Finally, the political elite behave the same all over the country. That's either a massive coincidence of bad apples or it's a systematic problem. Most people reading this would (and some probably do) behave the same in those situations.
