It occurs to me that the more politically-minded among my USA-based friends might have actually gone looking for newspaper articles on Australian politics to try to work out what I was talking about yesterday, and the odds are that you wouldn’t have got very far (the Brits might do better, since we inherited most of our political system from you in the first place).

So, for the curious among you, a  short explanation not so much on what is going on just now but on how and why it can go on in the first place.
