"Here's the problem:"

Nope, but nice try.

Your comment was "These same groups opposed Obamacare too. Nothing new here."

It doesn't matter if "AMA membership accounts for less than 25% of physicians in 2016" or was 100%

The AMA did not "opposed Obamacare too" which disproves your initial contention. 

They may be "in the minority" but they still disprove your initial contention.

You need to post something that supports your contention, not post something that is irrelevant as a diversion.
