Yes, advocates of health care reform should be concerned when they have failed to convince even a liberal icon like Susan Estrich to support their “reform” (hat tip, Kathryn Lopez).  She writes:

The president is “not familiar” with the bill. No one can explain how it will work yet, as Sen. Ben Cardin, D-Md., told a contentious town meeting. There are various plans, and negotiations are still in the early stages.

But whatever it is, we should be for it.

Am I missing something?

It’s an important point:  even if you believe in the idea of “health care reform” that takes us toward a “public” insurance system, shouldn’t you want to actually see how they are going to do it before signing on?
