Why would I be asked to provide evidence that physicians support the ACA? I expressed no position on that at all. My point is that the size of "n" gives you low statistical power and high variance in most of these surveys that we all know are of most interest to those with an axe to grind. The authors didn't, but you are extrapolating such a self-selected 1% response to a majority and then building other stuff on it. That I don't agree with, especially when you shoot down the AMA because it represents "only" 2200% of the survey sample you prefer. If I were an Obama fanboi, I'd be delighted to see people resorting to this sort of thing to mount an attack. That's it.
