"The point is a valid one. Dion has effectively put himself in a straight jacket when it comes to the environment. If elected he faces the challenge of fulfilling a promise he is incapable of keeping without shooting himself in the foot.
Or rather perhaps it's a question of just how much Dion is committed to Kyoto? Is he willing to put Canada into a recession? Is he willing to throw everything to wind, including for that matter rational thought, for the sake of his environmental principles? That's a question of character, which is only answered through trial and tribulation.
Regardless, Dion's predicament is aptly pointed out by Maddame Hébert.
That being said, Harper faces a tribulation of his own.
Harper, when it comes to the environment, is a victim of timing. He's the Prime Minister that's taken the reigns in the last days of "implementation" of the Kyoto accord. To many enviro-nutsos a failure to meet the commitments of Kyoto will be blamed on him.
The fact that the accord itself was unrealistic I doubt will be a conclusion for most.
If it had been a Liberal government in power until 2012 the enviro-crazies would have blamed Paul Martin Jr. The Conservatives would have seemed vindicated on their unpopular position on the Kyoto accord to many.
Fate seems to have decided that a single year extra of the Liberal Party of Canada was one year too much. And who can argue with fate?
