Liberals are just Conservatives with slicker marketing. 

They are naturally devious -  symbolized by their mantra of how they campaign from the left but govern from the right. They will say or do anything to gain or maintain office, spin the result if they win, and if they lose, nobody remembers what they promised.  

This is how they ruled Ottawa for most of the last century, and after a decade in the penalty box, they have shown that a young looking, gender balanced conservative party fronted by an attractive salesman still suckers feckless voters the way Chretien did when he promised to renegotiate NAFTA and end the GST.

With the Conservatives or the NDP, what you see is what you get - genuine conservatives or progressives.  The Liberals are a far slipperier fish.  Their 2015 polls and focus groups told them playing progressive would sell. So they became more "progressive" than the NDP. 

How's that working for real progressives and conservatives today?
