The AARP has always been something of a center-left lobbying group that consistently supports socialized freebies for the elderly. So this is not surprising.

The AMA is a little more surprising given that this plan will probably end up impoverishing many of its members. Not being a doctor I can't guess as to their inner workings. However, if its anything like the American Bar Association, the group is run by big city doctors and administrators who are just looking for a new form of corporate welfare and/or putting their democrat ideology over what's good for its rank and file members.
