I don’t think it’s self destructing NM, just re inventing itself, poll results certainly don’t say destruction.
It has a leader who is very temporary, he will fill the meantime gap and then be replaced. The Labour Party is Jacinda, remove her and it’s nothing, she is charismatic for sure and likeable enough. The public are cutting her slack because of smoke screens like babies etc, marriage will be the next smoke screen if the fog starts clearing, that will give her another 12 months. The danger if Win falls is she will be alone with the greens and that’s unpalatable to even many Labour voters.
Hesi will think I have flipped here but both Lange and Clark were necessary and ultimately good for NZ, Jacinda has her chance to leave a legacy mark on NZ like they did, let’s hope for all of us it’s positive.
