Whatever happens on Saturday, the 2017 election will be remembered because of Jacinda Ardern. She made it a contest. Only seven weeks ago the Labour Party was looking like it would not only be defeated, it was on the cusp of becoming just another small party. Ardern saved it from that fate.
She also changed the fate of other parties. When John Key decided to move on, Bill English took over as Prime Minister. This was a significant risk. John Key had been the most popular Prime Minister New Zealand had ever seen. Bill English led National to an historic defeat in 2002. As Minister of Finance he had established himself as stable and steady with none of the Key x-factor.
But it did not seem to matter. With the Labour Party in bad shape, National was thought by every commentator to be odds on to win the election. Who else could voters support?
The arrival of Ardern meant National had to lift its game. She forced the best out of English. National had to start thinking about how to fix the many problems it paid lip service to while pursuing the holy grail of a budget surplus.
Meanwhile, Ardern took the oxygen from all other parties. New Zealand First had aspired to record high support. The Greens had looked capable of breaking through their usual 10 per cent ceiling. Other small parties thought they had a shot at picking up votes that might have gone to Labour. The rise of Labour dashed these hopes.
