John Armstrong: Why is John Key still riding high in the polls? Put it down to several factors. First, an understanding of and empathy with the New Zealand character and what is acceptable and not acceptable. His moderate conservatism is straight out of Sir Keith Holyoake's textbook.
Key's second priceless asset is his finely-honed political instinct in which he has the sense to trust - even when receiving advice to the contrary. Few leaders who have spent six years in the job would have their feet still firmly planted on the ground. He is never aloof. Nor arrogant. He does not talk down to people. He can laugh at himself.
Key takes nothing for granted. Few other leaders would read polling data as avidly and earnestly as him. He also watches his opponents like a hawk. Behind the easy, ever-present smile is a very sharp intellect which can absorb copious amounts of detail - and then regurgitate it months later when circumstances demand.
With the equally unflappable Bill English alongside him, Key has projected calm and purpose in dealing with some of the biggest crises faced by a New Zealand PM. That has brought huge reward from voters. Key puts major emphasis on improving the things that really matter to ordinary people rather than the here-today, gone-tomorrow issues which titillate the fickle inhabitants within the Beltway.
Key's affable nature is not a false front to be worn solely for public consumption. But it does disguise the other John Key - the one driven by ambition.
