Blame it on Mighty River Power's plunging share price. Blame it on Labour's and the Greens' plans to intervene in the wholesale electricity market.
Those two factors have blown a hole in National's hopes of building a "shareholders' democracy" where citizens would lean more to the right politically because they would have a stake in privatised companies.
More than 420,000 New Zealanders expressed an interest in buying shares in Mighty River Power. Some 113,000 got around to opening their chequebooks to do so.
The number applying for shares in Meridian Energy, the second state-owned power generator to be put up for partial sale, is nearly half that at about 62,000. And only 16,000 of them are first-time investors.
Fortunately for National demand was such that a fewer number of investors sought bigger parcels of shares, thereby avoiding breaching self-imposed limits on foreign ownership.
