The faith schools controversy looked like a good idea at the time. There had been a court case earlier in the year about funding all schools tailored to people of different faiths, and it looked like a good way to score points with the ethnic voters that have very large numbers in many portions of Toronto and the 905 belt. However, thanks to McGuinty's fearmongering (helped totally inadvertantly - I think - but the Toronto Sun and the National Post), it blew up in his face, and his changing positions on this did more harm than good.
Boisclair's problems with weakness and inexperience apply double to Mario Dumont. He had no hope of a majority, and as a minority Charest would eat him alive. It showed rather clearly that the ADQ was a temporary blast to both the separatists (at the peak of the reasonable accommodation debate, separatists didn't look good) and to Jean Charest's crooked Liberals. Once Charest got some form back, the ADQ sank right back into the gutter. I know you want to see good Conservative fortunes there, but it ain't happening, and Rae instead of Dion probably has little effect in Quebec, aside from Outremont of course.
