Perhaps Palin would have more traction if she framed things this way:

Whenever you have nationalized health care, there is inevitably a slide toward scarcity of medical treatment. This has been documented in Canada and Great Britain, where doctors have emigrated en masse, more people flock in to get the free health care, and the end result is very long waiting times and sometiems unavailability of some forms of care.

In a situation like that, where more people request or require care than can be promptly helped, some sort of triage must take place. Certain patients and certain treatments necessarily must be given priority over others — just as in a battlefield hospital.

Who is going to make those decsions? What will the effects be? One could reasonably argue that some people will inevitably medically suffer (and perhaps even die) because their treatment was deferred due to the triage process. All as a result of the doctor shortage likely to loom under rnationalized health care.
