New Zealanders and Australians are fortunate: our current prime ministers may be standard bearers for the conservative side of politics, but they are pragmatists rather than ideologues and comparatively liberal pragmatists at that.
The Aussies are probably more aware of this than we are, since their recently-deposed leader Tony Abbott was a card-carrying member of the wild-eyed, doctrinaire tendency. New Zealanders who think John Key falls into that category should cast an eye over the 17 contenders for the Republican Party's presidential nomination: even the so-called moderates make Key look like Jeremy Corbyn. The rest make Colin Craig look like Jeremy Corbyn.
Both Key and Malcolm Turnbull have embraced causes not normally associated with conservatism. One of Turnbull's first acts on becoming Prime Minister was to scrap knighthoods and damehoods, which Abbott had reinstated a year earlier, while Key has led the campaign for a new flag. Indeed, without him there'd hardly be a campaign.
But these mavericks don't stray too far from the herd. Turnbull supports the current Australian flag - if you can't picture it, imagine ours with more stars - although his position has evolved: in the 1990s he was a director of Ausflag, an organisation set up to campaign for a new flag. (When he switched sides, an Ausflag spokesman said Turnbull epitomised the saying that politics is like rowing: you can face one way and go the other.)
Key is equally contrary but the other way around. It seems axiomatic that this inconsistency has compromised his advocacy since he can't present a new flag in the wider context of a big picture, forward-looking vision of nationhood and national identity. Conspiracy theorists are probably assuring each other the quixotic flag campaign is a calculated sop to progressive opinion offended by his restoration of knighthoods.
