Mr. Dion on the other hand, I believe, clearly understood the question to be a trap set by the journalist who clearly refused to reword the question. There was no good way to answer the question. Mr. Dion makes every effort to do this. He doesn't obfuscate when addressed by the media, he tries to understand the question and provide an answer with integrity.
If Dion had answered with integrity, he knew he would say that he would not have cut the GST and would have cut the income taxes instead. He also knew he didn't want that clip picked up and played over endlessly by the Conservatives right at this moment. Why, you ask, well with the visibility of the GST cuts, they have been mildly popular with the voters (that's why Harper did it, after all) who aren't paying much attention or do not understand economic issues.
In my opinion, Dion avoided saying "I would not have cut the GST" and have that be the last meme played for the last four days of the most important election for a progressive Canada. And he avoided being dishonest. I'd say, personally, that he is brilliant.
Personally, I didn't need any further evidence that Mike Duffy adds little to nothing of value to any discussion of importance BUT this little misadventure sure has exposed him to far more Canadians for the shill he is.
