And just because the Trump administration saw too many domestic pitfalls in an agreement that, by channelling even more jobs to Third World countries, would make it harder to "make America great again" doesn't mean the US won't re-enter the agreement and promptly re-animate some of its (currently "frozen") more draconian clauses.
For that matter, where are Labour's partners? Winston Peters - formerly a staunch critic of the "free trade" process - has been in the thick of the negotiations, so presumably has turned coat; whether his party will remains to be seen but, like the Greens, they campaigned firmly against it.
The Greens at least are staying true to their commitment to oppose the deal and have signalled they'll vote against it in Parliament, though they're playing down any rift as a "gentleman's disagreement" in this two-plus-one coalition.
So regardless of whether NZF also votes against or abstains we will see the previously-unthinkable: Labour and National acting together to push it through.
Sorry, but what planet are you on, Jacinda? Currently you're orbiting Planet Key. You won't find any more epiphanies there.
It's all very well for this flip-flop to be flippantly foisted off as an example of "the Maharey Rule" - "just the sort of thing you say in opposition", as former Social Development Minister Steve Maharey excused a change in tack under Helen Clark - when Labour called National's analysis of this agreement "flawed" and based on "wildly optimistic" scenarios which it promised - promised - it would fully and comprehensively reassess.
That hasn't happened, ostensibly because of time pressure. Yet there's no reason for unseemly haste; indeed if someone promotes a deal as too good to resist but says it's only available "for a limited time", surely that screams scam.
Most difficult to understand is how quickly and comprehensively Labour is moving to distance itself from its core supporters. For example the Council of Trade Unions says the TPP is still "structurally biased towards the commercial sector and downplays issues such as health, safety and human rights".
Whereas every even-vaguely right-wing commentator is falling over themselves to praise the Government for dealing with the devil.
Doesn't add up, does it? But apparently, this is what we voted for. Not.
