From an Angus-Reid survey on the impact of the Conservatives’ ad campaign on Quebec voters (emphasis mine):
Overall, the ads appear to have no effect on voting intention, although they do have a slight negative impact on attitudes towards Michael Ignatieff. Respondents who had seen the ad were 12 per cent less likely to describe Michael Ignatieff as strong and seven per cent less likely to describe him as open.
Respondents who had seen the Conservative ad were also less likely to say their opinion of Michael Ignatieff had improved (30%, compared to 39% for those who did not see the ad).
Regardless of whether respondents had seen the ad or not, the overall proportion of respondents who say their opinion of Michael Ignatieff has improved in the past four months (35%) is three times higher than any other federal leader (Layton 11%, Duceppe 10%, Harper 4%). The findings suggest that Ignatieff’s positive momentum in Quebec will likely withstand the current ad campaign by the Tories.
