Quebec can't find a municaplity that would be warm to the idea of having it's town be a port to export it. One place they were looking at was a breeding ground for Beluga whales and the government backed off after scientists said no no and environmentalist pressure. No municipality wants to be the port town.
New Brunswick may end up getting the exit port
The Irvings are against Energy East, so no way it ends in NB.
But I do genuinely believe that the PCs were not so much a place on the spectrum as power brokers under a big tent. And I don't see how that type of party survives when the tent is empty and the power is gone.
If Alberta history is any guide, they're screwed. Looking next door, the BC SoCred example (in power for 30 years, then they vanished) also makes it look pretty dire for them. And the Union Nationale in Quebec had an equally bleak outcome, though in their case they were so tied to Duplessis that there's a pretty big difference.
There are some positive examples, though. The Liberals were on the losing end of two of the largest majorities in history (Diefenbaker in 1958 and Mulroney in 1984), but they came back as big tent parties. Provincially, the Ontario Tories, too, came back after being in power forever (as the Big Blue Machine) & losing...though they came back as a hard-right party, which may have screwed them over in the long run, since now the party just keeps going more and more to the right and getting further and further away from power. And in Saskatchewan, the CCF -- not really a big tent party in the sense of the Big Red/Blue Machine or the AB Tories, but they lasted forever as a political dynasty, so there are some similarities -- was able to stay relevant after losing, then come back as the NDP and become another dynasty. They're being killed by Wall now, but I think they'll come back eventually.
So...yeah. I'm buying into your thinking, that the Wildrose will overtake/succeed the PCs, but it's not out of the realm of possibility that they stick around and come back.
