The BC Federation of Labour sponsored a poll conducted by Environics. They surveyed 854 people between August 29 to August 31st and asked a series of questions about the strike, and then asked about voting intentions. The only link I have to the survey is a news story (link).
The survey has the following result:
If a B.C. provincial election were held tomorrow, which one of the following parties would you vote for in your constituency? (Factoring in leaners. Factoring out non-voters and totally undecided)
BC Liberals by Christy Clark 25.4 %
BC New Democrats (NDP) led by Adrian Dix 44.8 %
BC Conservatives led by John Cummins 19.8 %
BC Greens led by Jane Sterk 7.8 %
Other 2.2 %
Without knowing the undecideds and non-voters, one doesn’t know the “real” working sample, but take this survey for what it is worth, it is roughly consistent with other polling done.
