It's the problem of U.S. politics. You have to possess certain pathology to want that job, even at the local level. It's so connected to your response to people around you that you become this thing that is always "on" and always on the hunt for opportunity, press, and money...
Then again, maybe it's not that different rom what we do. The difference is, we think all that groveling is bullshit and do it as a means to an end. The political people get corrupted by it.
