The Act Party has taken a desperate step by declaring at this early stage that it will give National another confidence and supply agreement after the election. This is the first time the party has committed itself to such an agreement before the ballot rather than waiting to see what it might do with the votes it receives. It is a decision Act will not have taken lightly.
It weakens the party's ability to bargain for any particular policies or cabinet positions after the election, as leader Don Brash concedes. The decision was made, he says, to give voters an assurance of stability. Act wants to give them no reason to fear it would cause any complications for National in a second term.
Clearly the party has discovered that very few of its possible voters want it to be the force that Dr Brash implied it might be when he took over the leadership a few months ago. Its position in polls has not improved since the takeover. The party's only prospect of survival remains the Epsom electorate where it has replaced one of its founders with a National Party veteran.
The pre-election commitment is an admission that Act's only purpose now is to support National. It has been reduced to the same role that Jim Anderton's Progressive Party has performed for Labour. MMP allows a safe seat for National or Labour to be worth two or more votes in Parliament if the seat is given to a loyal supporting party. Mr Anderton, long after he was reconciled with Labour, maintained the fiction of an independent party for just this purpose.
In latter years he could not win enough nationwide votes to give Labour additional seats but continued to enjoyed a foothold on the national stage, taking part in television leaders' debates though he represented nothing more than any other electorate MP.
