Nice piece on what it takes to be an effective leader in a democracy, not just applicable to the U.S. experience. At some point a true leader needs to be able to say "You know what? I screwed up. I learned from it, I've fixed it, we're moving on. If I have to take the lumps, so be it." Problem is, when you own the parliament there's no longer any reason to feel yourself accountable. That's when you get the responses like we've seen in the last few days.
