Interestingly, in the NBR on Friday, Matthew Hooton writes of a polling trend internally in various parties that on election day has Labour down at 20 and New Zealand First at 20. Sounds absurd, and it isn't backed up by last night's poll. Last night, New Zealand First went exactly nowhere.
But as to what Labour do, it's simple. Double down, they're stuck, there is nothing they can do. They have said all along Little is their man for this election. If he isn't, that means panic, and panic means voters scatter.
They have been here before of course - the famous Mike Moore instillation, a handful of weeks out from the vote of 1990. Here in 2017, can Labour, in all honesty, look at Grant Robertson and Jacinda Ardern and go "there are our saviours, they'll make all the difference?" No, they cannot.
And I think the cold hard reality is that Little is not actually the issue. The entire Labour movement, the PC takeover, the blancmange veneer that is modern Labour is the real issue.
It's not over of course.
And although one poll is not the whole story, I suspect this is the start of a trend, and the trend is the beginning of the end of Labour as an automatic major political force.
