According to Angus Reid:
Parti Quebecois: 37% (-3%)
Liberal Party of Quebec: 32% (+11%)
Action democratique du Quebec: 13% (-)
Parti vert: 9%
Quebec solidaire: 7%
The changes are from November 2005 and, if I am not mistaken, the original article contains an error, either in the Liberal Party gains since November (which it claims to be nine points), or in the November 2005 Liberal Party figure, which is given at 21%.
I don't claim to understand the electoral dynamics of Quebec, but this looks like minority government territory. If so, I wonder how that would effect the timing and possibility of any referendum question?
