The most devoted readers of Jeffrey Simpson were delighted that he wrote his Globe and Mail column on Tuesday about Arnold Schwarzenneger's decision to run for governor of California. It was an event that needed to be viewed with alarm and disdain, in the Simpson manner, and he did not disappoint us. He never does. He polished off, in 14 paragraphs, not only Schwarzenegger but also populism, the culture of stardom, and California's "perversion of progressive politics" -- which, as any Simpson reader can tell you, is inferior to the politics of cabal and indifference by which Canada is run.

Simpson's tone reminded us once again of his unique place in the national political culture of Canada. Far more than a mere newspaperman, he has achieved over the years roughly the status of a senior deputy minister. In Ottawa he functions as deputy minister of opinion. He holds no government post, but that's a technicality. Having written his column since 1984, he outranks, on longevity alone, every other deputy in Ottawa. Moreover, he shares their attitude to governments and politicians. He knows even the most powerful politicians are only temporary. They come and they go. He remains.

Like all deputy ministers, he believes above all in what he calls "sound public policy," the phrase he used on Tuesday to describe one of the many qualities he finds lacking in the government of California. And, like all DMs, he automatically views with the greatest suspicion anything to which he is unaccustomed. Schwarzenegger's great crime is his strangeness. He fits no common pattern and might well go in some unexpected direction. He seems decent enough for a movie star, he's done nicely in business, and even if he proved to be an incompetent governor he would at least be an amusing incompetent -- a distinct improvement, I would have thought, on the boring incompetent now holding the job. But Simpson intensely dislikes populism, which means government by people civil servants regard as unsound. (The last populist to be PM of Canada, John Diefenbaker, kept the entire Ottawa public service traumatized for the six years he held office, 1957 to 1963.)

As for California, its greatest perversion is the habit of making laws through plebiscites rather than through legislatures and judges. Deputy ministers live by a truth they learn in their youth, ideally (like Simpson) at Queen's University: It's dangerous for a democracy to put decision-making in the hands of the people.
