THat's true, but part of what can help the BQ to win sme of those Conservative seats is if Liberal support rises at the expense of the Conservatives and BQ candidates come up the middle. Last election, the Tories won most of the seats in Quebec City. Most Quebec polls show that the BQ is now in first place in QC with the Tories and Liberals tied for second place.
Yes, what was a huge tide of Conservative support in the Quebec City region in 2006 has been deteriorating over the past year.
I don't think the Liberals mind if the BQ take the Conservative seats in the Quebec City region actually as it will reduce the national Conservative seat total. The only seat in the Quebec City region that the Liberals are targeting this year is Louis-Hebert.
