The Canadian Press Harris-Decima survey indicates the Conservatives actually increased their lead over the Liberals, despite days of highly charged politicking over the dealings between the former prime minister and the German-Canadian businessman.
The poll, conducted last weekend, showed the Conservatives with 36 per cent support, compared with 28 per cent for the Liberals.
The NDP were at 17 per cent, the Greens, 11, and eight per cent of respondents backed the Bloc Quebecois.
Last week's Decima poll for context:
The Canadian Press Harris-Decima survey put popular support for the Tories at 33 per cent - well short of majority government territory - with the Liberals at 29 per cent.
The NDP was at 17 per cent, the Green party at 12 and the Bloc Quebecois at eight.
Anderson said the provincial sample is small enough that drawing conclusions from a single survey is iffy, but the trends are clear over three weeks and they show the Tories challenging the Bloc strongly.
"You could probably make the case that in Quebec, where the Conservative numbers have shown up pretty strongly this week, that we do know that Quebec voters are pretty fed up with allegations of corruption and scandal and that sort of thing," he said.
"It's probably reasonable to assume that they like the way that Stephen Harper reacted to the Mulroney affair."
He said the Tories seem to be making progress in Quebec.
"On balance, it looks like those nationalist Quebec voters, those BQ voters from previous elections are saying that the Conservatives, so far, are on the right track."
This is all margin of error stuff, but if you look at the apparent uptick, Quebec might be the key. Mulroney is a different entity in Quebec, than in the rest of the country, so the government may be less vulnerable. Last week Anderson was cautioning that the fallout of the Mulroney affair wasn't fully reflected in their poll, this week would give a clearer picture. At the very least, further evidence that this entire affair has been met with a giant yawn from the people.
