Is the surge in support for the Greens the result of the party doing most things right? Or is it simply down to almost everything going wrong for Labour?
Week in politics
For the past three years, Phil Goff has tirelessly pushed his boulder Sisyphus-like up the hill, only for it to roll back down each time.
It's welfare reform, Jim, but not as we know it. National's first substantial foray into territory from which it fled in undignified retreat in the Ruth Richardson-Jenny Shipley era is very cautious, very measured and very unthreatening - deliberately so.
Mission impossible? The green light may have been given for a long-awaited parliamentary inquiry into the price of milk, but the approval may have come too late for the commerce select committee to come up with any findings before the election.
The Labour Party does not have very much cause to feel grateful for anything right now. But it should get down on bended knees and thank the Almighty that hardly anybody would have been watching Parliament late on Wednesday afternoon.
To brand a political opponent as destructive and duplicitous is a bit rich when you subsequently pilfer a couple of his party's key policy planks without even a word of acknowledgement.
So begins the new season of that political sport known as "the tacit nod" - the hints of varying hues of subtlety which political leaders give their followers to vote a certain way to either decrease their opponents' chances or increase those of their allies.
Chalk this one up as something of a triumph for Phil Goff. So far, at least.
Phil Goff is not just risk averse. He is risk-phobic.
National's first move towards gutting state housing?
It may not be the done thing to go into bat for Gerry Brownlee. But a lot of the stick he has been getting as Earthquake Recovery minister has not been warranted.
Election? What election?
Such is John Key's Midas touch, he could probably sell ice-cubes to Eskimos - and at a premium price. Selling the merits of even partial privatisations to once-bitten, ever-shy New Zealanders ahead of the November election will be a far tougher test of the Prime Minister's undoubted skills and acumen.
It may sound barmy, but maybe the Treasury should be added to the list of state assets National has singled out for post-election share floats.
This was classic attack politics. You get in first with your version of events. In a sound-bite democracy no-one remembers your opponent's rebuttal.
John Key and his National Party colleagues may well take a hit in the polls in the wake of Thursday's mediocre Budget.
Bill English's third Budget will be tough, perhaps the toughest in a generation. But this next Thursday's document won't be as tough as people fear. Or as tough as people have been led to believe.
If the law is an ass, then Parliament's rules are sometimes as stubborn and stupid as a pack of mules.
How many more times is TV news going to repeat that clip of an ungainly-looking Don Brash slowly and awkwardly squeezing into the driver's seat of a midget car at Auckland's Western Springs speedway in 2005?
For the first time in quite some time, the National minority Government this week looked a bit ragged around the edges. Not hugely so, mind you. But wariness seems to have succumbed to a degree of weariness.
