>>Nick, there are over a dozen different major surveys over the last several years. Anywhere from 55% to 75% of licensed physicians in the U.S. oppose some or all of ACA.
>>Stated another way, there is no evidence to indicate that the majority of licensed physicians have a positive view of it. (Or for that matter, no evidence that a majority of Americans have a favorable view either)

No evidence? I think you're stuck on those early "lets have a survey and claim that a 3% self-selected response represents the majority." Also it's a fact that physicians were dissatisfied with admin and insurers before and after the ACA so it's another whopper to claim that dissatisfaction relates purely to the ACA.

Even so, in more recent surveys such as Medicus, 83% of physician respondents say reform is working in 2015 compared to 77% in 2014 and 70% in 2013. But it's the same issue I've raised before: with only a few thousand responding to a voluntary survey, Stats 101 says you're more likely to get disgruntled respondents along with retirees and others who have the time. Busy physicians file it in the trash. IMHO all you can read reliably is the trend: physicians are warming to the ACA.

If you look at the Kaiser Family poll, something else emerges: physician opinion re the ACA almost matches the general public's and the most reliable determinant is: Democrat vs Republican. So if you see a physician ranting about the ACA, the most reliable conclusion is that they're Republican.
