It's about the CBO saying that the plan is going to be a lot more expensive than Obama is saying.That may be true but what does that have to do with savings from transposing the Canadian system to the US, which is the point you claimed was refuted?
A cynic might conclude that people are pigeonholing a whole lot of different ideas under a demonized "reform" label so they can damn them all.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
