Consider the source, obviously--the Pembina Insitute has an agenda. Nevertheless, this poll confirms what most polls have been showing over the past couple of years:
Canadians are warming up to the prospect of paying an environmental tax on activities that cause climate change, but they don't necessarily expect to get the money back in the form of income tax cuts...
Steve ("the poll guy") V. at Far and Wide has been writing extensively about how Dion's environmental proposals might play out in the political arena. Read this post especially, in which he makes a case that the fact that opinion seems to be swinging the Libs way at the moment is all part of some brilliant strategy. I myself think its just good luck (and esp. some bad moves by Jack Layton), but admittedly the result is the same.
Not that things might not change. Paying a tax in the abstract is always easier than paying it in the real world.
