Actually having time to read for pleasure right now, I've been reading John Crosbie's, a Mulroney-era minister, autobiography No Holds Barred.
And this piece of information, a Decima Poll, around August 1993, two months after Kim Campbell became leader of the Progressive Conservatives and Prime Minister, is really interesting to me:
Decima Poll, among decided voters,:
Progressive Conservatives 35%
Bloc Quebecois 9% (33% in Quebec)
Source: John Crosbie, No Holds Barred: My Life in Politics. Page 457.
We know the result of that election, in October. The Liberals won a majority government.
The interesting question is: can parallels be drawn from this poll from the past and recent polls?
