Has to be said, when it comes to playing dirty, no-one does it like the right. They don't stop at dirty tricks, smears and manipulation of their opponents. That would be expected. They do it to their own, with out qualm.
Consider: Kim Dotcom tried to buy his way into influence, with generous donations to John Banks. In reply, the right set the police on him, froze his assets and destroyed his business, at the behest of the US. He discovered that the right only owes loyalty to the most powerful.
Bevan Chuang fought to represent the right in Auckland; when they failled, they switched to Plan B and used her affair with Len Brown as a means to attack him, in the meantime destroying Chuang's credibility and budding political career. She discovered that if you can't be useful to the right, you can still be used.
And now Jock Anderson has been wolved by the NBR for daring to suggest that Len Brown should get on with his job. Apparently, that's not neutral and unbiased. One has to assume, the NBR employed Anderson to be stupid, and on this occasion he was not stupid enough. Nothing else makes sense. He discovered that the only liberty the right tolerates is the liberty to toe the line, or be trounced.
