Tova O'Brien: David Seymour overtaking Judith Collins as preferred Prime Minister is the political death knell

OPINION: A confluence of crappy calls has delivered Prime Minister Jacinda Ardern's Government this venomous verdict from voters.

She knows she needs to take notice - actually listen, and not be glib or flippant about this crystal clear public feedback.

Which is why Ardern took the opportunity in our poll interview on Sunday to hint at upcoming changes to the border - letting in more skilled migrants, allaying some of the fury from the agriculture and horticulture sectors. 

Ardern does not want this popularity tanking - which Labour is also seeing in its own internal polls - to become a trend and for the rot to set in. 

That said, with that pathway to power still locked in thanks to the Greens, the biggest story here is less about the left and more about those ructions on the right.

Elections are fought and won in the middle - at the moment National, ACT and New Zealand First are fixated on a lot of the same further-right issues.

But it's not actually a terrible tactic - it's classic election cycle stuff - firm up the base in the first year after an election loss and move to the centre to try and scoop up the rest as you get closer to polling day.

Labour did the same when it was in Opposition.

And there are other similarities with that time: Labour's leadership was such a shambles that the smaller party leader - the Greens - became the de facto leader of the Opposition.

In politics, history definitely repeats. So, like Labour back then, National MPs now will be squirming at the prospect of nine long years on the Opposition benches.

Judith Collins has failed to claw National back in the polls and now, being overtaken by ACT leader David Seymour, that's the political death knell.

Listen out for the murmuring at next weekend's National Party conference - sooner or later, those murmurs will turn to mutiny.
