The reason that NSW Labor has survived as long as it has is because the alternative is; NSW Liberal. And that's as bad, if not worse. At least the factional leaders of NSW Labor, right-wing as they are, aren't card-carrying members of Opus Dei who refer to Lebanese people (publicly) as filthy camel-****ers. Many of the leaders of the NSW Liberals are.
If the people of this state had even a modicum of intelligence they'd simply vote Green - or at least some third-party, I almost don't care who, even that nut-job Fred Nile would at least scare the crap out of the major parties and make them change their ways - and oust both major parties. But, as anyone who's lived in this state for very long would know, intelligence is a commodity which is scarcer than the Philosopher's Stone in this hell-hole.
There's an old saying about there being no such thing as an honest politician. In NSW, we'd happily settle for a lying bastard, so long as they were competent. We've yet to find one.
