Medicare For All, Whatever That Means

The authors of the Upshot article on the many shades of "Medicare for All" at the NYT have performed us all a service by attempting to show five different important policy and design distinctions inherent in refining a definition of "Medicare for All."  The only the part that is missing is showing what relationship whatever topic is being discussed bears to Medicare as we currently know it. For instance, Medicare as we know it, does not have automatic enrollment yet carries substantial penalties for late enrollment. It would be useful to see what percentage of respondents would like that carried over to "Medicare for All"– either in the interests of intelligent plan design or political palatability.
