I was there for Harper; remember the barbaric cultural practices hotline? Remember the fisheries library just being tossed? The only contender for further left is Lester Pearson (by the standards of his time), who brought in the healthcare system. I'm not even being original here, it's pretty standardly what you'd hear from a pundit.
I’m arguing that the Liberals acting like conservatives makes the conservatives tack even further to the right, and we slide and slide into late stage capitalist hell.
Just looking around the world, I'm certain the right is pulling, not being pushed.
