The best people to watch over the quality of our health care system are not the hon. members of the Liberal Party, but the citizens who, along with the various provinces, will put pressure on the government and their local representatives who are involved in the health care system.
Politicians can't always be relied on.
Since the citizens do a better job of overseeing health care than members of the Liberal party [politicians], politicians can't ALWAYS be relied on [since some politicians are Liberals]. The model missed this logical inference.
