It is National's misfortune that the smelter's future impacts on the two most crucial issues currently confronting the Government; first, creating jobs, not culling them; second, partial privatisation and whether a perceived electricity glut dampens small investors' enthusiasm to take a punt on shares in Mighty River Power.
The politics dictate that the smelter be saved. The economics argue that it should sink or swim without ever more concessions on power pricing.
Key endeavoured to straddle both positions yesterday. He spent the day front-footing in the media, offering far more information than is usually the case in such secrecy-shrouded negotiations. He was fulsome in indicating Meridian and Rio Tinto were far apart when it came to agreeing on longer-term pricing. He was emphatic that his Government was not interested in providing a long-term subsidy.
In part, Key was deliberately engaged in a softening-up exercise to attune people to the very real possibility of the smelter being shut down for good.
He was also telling Rio Tinto that the Government was neither ideologically inclined nor financially capable of propping up the smelter - even if some 3000 jobs in Southland are under threat.
In part, he, like Rio Tinto, was indulging in brinkmanship. His message to the multinational was crystal clear. Two can play at that particular game.
