Word on the street is that Paula Bennett, after her stellar fundraising efforts before the election is being bought in as National Party President to replace the rather hapless Sylvia “Who” Wood.
In fairness to Paula she is a good fundraiser and wonderful at ratfucking caucus members who aren't doing what she wants them to do. Apparently the caucus are a bit worried none of them are quite good enough to knife Luxon, so they are colluding around the Bennett campaign for Party President so they have someone who can deliver the bad news to Luxon.
Paula will be the one who pushes Luxon in front the train. Shouldn't be too hard really, I mean she's already literally pushed a person onto the tracks before, so why not another?
The president is usually the one that is asked to have a quiet chat to the leader when the numbers are against them. Judy Kirk was heavily involved in showing Don Brash the polling that showed he would never win and National would gain more votes without him.
The same happened with Jim Bolger, when caucus rolled him while overseas, that's how courageous they weren't, it was put on my old man as he was president at that time, to go give Bolger the bad news because none of them had the stones to tell him themselves.
In an ideal world the party wouldn’t need a new president to get rid of Luxon. They would just do it. But it is a convenient cop out that allows them to give Luxon a few more months to well and truly hang himself with high net negative favourable numbers.
