Sure. I should probably preface it by saying that negative information isn't necessarily inherently bad. It is actually useful for Canadians to hear things, even if they're not always positive. The thing that concerns me is the fact that you can spend advertising dollars during an election campaign, and a fair bit of that money is essentially subsidized by taxpayers, either through the fact that donations to political parties are tax deductible, or because a portion of the spending is returned after the fact if you meet certain thresholds.
Effectively, what that means is if very negative information is occurring, the public is subsidizing that negative information. The question for me is where we draw the line. How do we even define what is negative or beyond the pale? I haven't seen any research about this, but I have to assume most Canadians would not want their taxpayer dollars going to support blatantly negative advertising or other negative activities.
That's what that comment is about.
