Are you accepting that Obama will get the savings, then, and that those NHS anecdotes will be relevant because we'll be looking at massive cuts in total US healthcare spending, not just a reduction in the rate of increase (which is more like what Democrats are claiming).

If you want an apples to apples comparison, you should be looking at high-spending systems since even with savings claimed by Democrats, we'll still be spending far more than the British. More even than high spending sytems like Switzerland or Denmark.

Plenty of opponents are arguing that we will get NHS-style outcomes but also complaining that we will be spending EVEN MORE than the US does today.

To do that, you have to assume that our system will become massively less efficient than it already is. That we will be far, far less efficient than the British NHS.
