Call me slow, but I just keyed into something. Harper is extremely vulnerable right now. The opposition can let Harper's suspension of parliament go through.
And then blitz the country with Ads. "Harper and the Conservatives are taking a vacation to watch the Olympics." As much as it bugs me to mention this, but they have to avoid all mention of Afghanistan, detainees, and anything else policy related. Keep the message simple. Emphasize that the Conservatives are shirking their duties.
This message will resonate. It will kill Harper's "Tim Horton's" man mystique. His defense is none-existent. He can only bluster about "reformulating policy". Trying to point out that the opposition made him do it, won't work this time. There was no threat from the opposition. Any attempts in this vein would look like the petulant whining it is.
Even when parliament resumes, they keep to this message. The Conservatives took a two month holiday when Canadians were out of work and in dire financial straits. Hammer at it constantly, eek all the mileage out of it they can. (In the meantime they can still keep at the detainee issue, but keep the message in the press about how the Conservatives avoid working whenever possible.)
The Conservatives apparent mystique is the common-man image. Hit him where they're strong, and the polling numbers will follow. Now is the opportunity for the opposition parties to control the debate, control the message in the media. Do it right, and the Conservatives will be nowhere near forming a government next election.
