Fatigues...when exactly did the Canadian public vote 72% in favour of C-15? Nobody seemed to notice it get voted in...
They are opinion polls of course. In 2007 the support for mandatory minimums was just north of 71%.
In June 2009, support for six months minimum sentence for growing five to 200 plants was at 63%. By that time, the Commons had already passed Bill C-15.
There is significantly less support for "five to 200" plants resulting in mandatory sentences than there is for larger sentences for larger grows, where suport is at 72% and 73% as late as June 2009. As I mentioned, News Flash: Canadians Don't Like Drug Dealers.
I suspect that if there was more finely tuned polling and more public education, you might target polling to justify a push for increasing minimum numbers up to 15 or even 20 plants, say. That would have been extremely useful advocacy, once upon a time. But of course, it's the government paying for these polls, so they are not likely to conduct public opinion polling which tends to make their policies look bad.
Instead, that's the role of effective marijuana advocacy groups: something that does not exist within Canada. And so effective media communication combined with targeted polling to modify government policies -- and the policy of the official Opposition - the Liberal Party of Canada, was never attempted.
In any event, that's what politicians do; they conduct and listen to opinion polls to both establish and justify their polices. When their numbers go down, they frequently adjust their polling questions - or adjust their policies, or both.
Political opponents use polls to influence the public debate and shape media and public perceptions. They can be very direct and blunt instruments - or very subtle weapons. But in either case, they are expensive. That requires organization, credibility and financial success. Traits that are difficult to ascribe to the so-called "marijuana movement" in Canada.
