Of all the self-inflicted crises, sideshows and distractions that have bedevilled National this year, the "extra pokies in exchange for a national convention centre" wrangle is something of an exception. It has one very prominent character who is central to the action - the Prime Minister. And that ups the political heat to pressure-cooker levels.
John Key's response to the news that the Office of the Auditor-General will conduct an inquiry into how SkyCity became the preferred bidder for the construction of a national convention centre was accordingly to play down its significance.
The worst thing would have been to appear defensive and besieged. Key instead made light of the inquiry. He welcomed it. He expressed confidence that allegations of shonkiness, cronyism and short-circuiting of established tender practices would be proved to have no foundation.
The Prime Minister is gambling on today's "Key embarrassed" headlines turning into "Key vindicated" headlines after the inquiry's findings are released.
The convention centre is the Prime Minister's pet project. He is up to his neck in it. Even the mere hint of anything remotely dodgy will be a huge blow to his credibility - and quite possibly a lasting one.
