A vote for Peters is a vote for a Labour Government
One News summed things up well last night I thought. They picked up the significance of National effectively ruling Peters out. It removes NZ First as a kingmaker who chooses the Government.
They concluded that what this means is that a vote for NZ First is effectively a vote for a Labour led Government.
And if NZ First make 5%, it is almost impossible on current polling for Labour to form a Government, without Winston.
