The election we are to have in six months time has become, it seems, a competition to define that all-important marketing buzzword of the moment: "authenticity".
Policies and ideas should, as always, be of prime importance. But Cunliffe v Key seems to have come down to a contest between perceptions of two men who both grew up in modest circumstances before doing extremely well for themselves. However, while one of them seems comfortable with his good fortune, to the point of stupor, the other suffers because of it.
One Labour man who was entirely and authentically a "man of the people" and never had to fear persecution for his back-story was Norman Kirk, Labour leader and Prime Minister for just 20 months from 1972 to his death in 1974.
As chronicled in an excellent new biography by historian David Grant, The Mighty Totara, Kirk's experience of his family's suffering during the Great Depression propelled him to public office, even though he left school at 12. Of his essentially socialist beliefs he later wrote that "some of my strongest memories were formed of the stupid cruelties that rationalised conservatism could inflict ... they didn't know the answers. They believed there was no answer."
