Canadians of the future -- and no doubt, foreigners of the present -- will be amazed to learn that the colour of margarine has been a lightning-rod issue in Canadian politics, bundled up with such things as French-Canadian separatism and good old-fashioned protectionism for the dairy lobby.
It has literally come to police raids on Wal-Mart grocery sections in Quebec City. But glory be, the people of Quebec will soon be able to enjoy yellow margarine like the rest of the world.
If you're really interested (and there's no good reason to be) there's some decent background here.
In my homeland's defense, this is at least an issue of tangible reality, unlike the fantasies that seem to preoccupy American politics: Does Barack Obama love America or the Prophet Muhammad? Can Social Security be saved from disgrace? Etc.
