Yeah, in looking at the 1993 results, the Liberals did well in a few rural Saskatchewan seats (only winning in Souris-Moose Mountain but weren't far behind in most ridings). But, those days are long over.
That's an interesting pattern on its own. It seems like when there's a 'throw the bums out' election, the winning party will overperform in some places where they have no roots, and immediately return to their normal level once they aren't running against an unpopular incumbent or riding a wave.
The Liberals in the Prairies in 1993 is a good example of this. So is the Tories in parts of Quebec in 2006. What would be the equivalent example for the 2015 Liberals?
It's kind of tough to tell, since we don't know whether an unusual result is part of a realignment/demographic trend or just a fluke. I'd guess the nationalist parts of Quebec or rural BC.
