Reasons why the Conservatives seem to be making significant gains in Quebec?

I understand that the Liberals are unpopular, and the Bloc seems to have outlived its perceived need. I also understand that the Conservatives have put "distintct society-like" measures through parliament.

But, why have the NDP not made gains?

My observation is Quebecers seem to look to government to intervene in many areas to protect citizen's interests. Unions also seem strong in Quebec. The citizens also seem to be mostly anti-Afganistan, pro environment. and cool on the monarchy.

The connservatives seem to register low marks on all the issues above.

But, the NDP seem strong on those issues. Yet, it cannot seem to connect with voters in Quebec.
