I see you aren't a fan of PR either. You know, the reform JT promised in 2015.
Priorities and promises change with the weather. I'm more into looking for a Liberal party move to either the left or the right.
The Liberals and the Conservatives will usually do that which brings the most support from the people, and then revise their moves later to be in tune with their politics.
So for instance with the Conservatives: I can see them being all for upholding our universal health care system and then after winning an election, start bringing in a two-tier system.
Or you could probably think up some other scenario on how the Liberals would need to lie and then backtrack?
