From the Herald today;
Mr Key may also get the chance to be lampooned by talkshow host David Letterman and will meet his old nemesis, Helen Clark.
Nemesis: something that a person cannot conquer, achieve, etc.: The performance test proved to be my nemesis.
So obviously this journalist and subbie are not classic scholars, or simply have not comprehended that John Key has a life time undefeated record against Auntie Helen and always will, and in fact it is fair to say that John Key is in point of fact Helen Clark’s nemesis.
