Most political polling this year has shown Labour support going up slightly in a predictable version of the bounce you will get when you throw a dead cat from a high building. The Greens have also gained support in many polls. Naturally, the Government is losing support - that is what governments do when they govern. The Labour vote should be hitting the ozone layer by now.
That any National voters at all can opt for the Greens in preference to Labour must be deeply concerning for David Shearer and his small band of followers.
The Labour Party did itself out of a job years ago - not those after 1984, when it betrayed its supporters with Roger Douglas' economic sell-off of the country, but in the years following its return to power in 1999, when it failed to reverse or otherwise reject those reforms in any meaningful way.
Helen Clark dragged her various coalitions through three terms by sheer force of personality and a brilliant back-slapping, hail-fellow-well-met shtick she could turn on whenever a camera turned her way. She and her Finance Minister, the future Lord Cullen of Kilda, made the most of buoyant economic times to finance the Cullen fund and some populist benefit twiddling.
Personality is no longer enough, so Labour has experimented with lack of personality. That hasn't really worked out for them. David Shearer could have Cary Grant's charm, Barack Obama's charisma, and Moses' ability to drag a reluctant population behind him - it wouldn't make any difference right now.
