i don't buy that for a second. it's pretty clear to me what the greens and the ndp want from this country for the next 10 years.
there is a lot of overlap between the tories and the grits, but that doesn't mean they aren't clear about what they stand for either. 20 years is a hell of a long time for a political party to be looking forward in terms of a political platform. can't say i can remember any politicians having that long-term a vision.
that said, there have already been - even this early in the campaign - several long-term policy announcements thatr illustrate different views on the political (and especially social) direction of this country over the forseeable future. education, health care, immigration, urban development, debt reduction, the economy - these are some of the most central issues, and fairly clear policy directions are widely available.
