Good for you conceding graciously and resigning.
You've learnt enough in politics to resign in dignity, as you've done worse. 1996 saw Labour's worst ever result with the first campaign you led the party into, in the meantime you have managed to decimate virtually every party you govern with - the Alliance and NZ First out of Parliament, United Future a one man band along with Jim Anderton. However, your greatest victory must surely be to have essentially "won" with the punters on policy. You got re-elected twice after increasing taxes, increasing the size of the state, pouring people's money into expanding welfare, state health and education, and increasing regulation and subsidies. It is what people wanted. National has been elected, largely on a platform to not alter what you've done in most cases. No privatisation, no essential change in state health and education, no end to Working for Families, Kiwisaver or the Cullen Super Fund. No end to ETS, or the anti-nuclear policy. Imitation is the highest complement, so you shouldn't fear your legacy - National was not elected on dismantling it. The views I support did not win National the election.
You've led three governments I have, almost without exception, disagreed with vehemently. You changed the law to get around the illegality of campaigning in 2005 with taxpayers' funds. You implemented many policies unannounced at the previous election. However, most of all you regarded the "state as sovereign", your love of the state and what you think as it being helpful has appalled me, but I give you credit for one thing. You still have some principles you hold onto dearly, and you, by and large, have stuck by them. Trade unions, state provided health, education, welfare and housing, state directed spending on the arts, telecommunications, transport and embracing the ecological agenda. A barely shrouded dislike of US foreign policy as well, has been part of your administration. If there is one thing to admire about you, it is that you've believed in all of this, fought it, and been determined to be consistent about that. It is more than most National Party leaders do.
So I hope you step back, resign as member for Mt Albert appropriately, and write a book. I hope, as you'd expect, that the National/ACT government does dismantle much of what you have done. That does not include civil unions and legalising prostitution - though neither measure was a government one, they were measures that did advance freedom a couple of steps. However, freedom is more than that - it is the chance to make your own choices about how you spend your money, about you and your families healthcare and education, and about adults interacting voluntarily - not having a finger pointing nanny telling them what's best. New Zealanders deserve far better than that. You spent nine years enjoying a healthy economy because of what two previous governments did to ease the size and extent of nanny's pointing finger - the free ride is over.
Goodbye, farewell, amen to you - but your policies? Well, don't worry too much.
