At 25 per cent or thereabouts in the polls, Labour is not in a position to be ruling any parties out of a possible coalition. Yet David Cunliffe seems hell-bent on doing just that. First the Internet-Mana alliance was ruled out, then this week it was the Maori Party. Mr Cunliffe declares he will have only three parties in his government - Labour, the Greens and New Zealand First. Why is he doing this?
It cannot be simply that he wants to dispel the image projected in National's advertising of a Labour-led coalition of disparate misfits. If Labour is to have any chance of leading a government after this election, it will need every small party it can muster. By ruling out two of them, Mr Cunliffe shows he is not looking beyond the election. He is concentrating on limiting the likely damage to Labour at the election. Spurning the Maori Party and Mana might help Labour hold on to its vote in the Maori seats.
It also enables Labour to keep alive, just, the possibility of working with Winston Peters, who has said he will not be part of a government that includes either of the "race-based" parties. But Mr Cunliffe has probably done Mr Peters a greater favour than the NZ First leader will do for him. Mr Peters has not exactly welcomed his inclusion in Mr Cunliffe's imagined ministry.
Mr Peters, like Peter Dunne, is clearly pitching his campaign to Labour voters who do not expect Labour to be forming a government this year. Both have discovered how rich the pickings for their parties can be when the electorate is not in a mood to change the government and supporters of the main party not in power are looking to use their vote differently. United Future and NZ First each had a good haul of seats in 2002, when National's vote fell to 21 per cent.
