I wouldn't go that far, personally. Well, with respect to the "old guard" of Democrats, yes.

But Bernie Sanders' position on health care was essentially single payer (https://berniesanders.com/medicareforall/). And he did quite well, particularly with the younger voting bloc.

From a perspective of "the left" overall, I think the seeds for single payer might be a little stronger than you think. That's especially since opinion polls seem to indicate single payer systems are fairly popular. (http://www.gallup.com/poll/191504/majority-support-idea-fed-...)

Whether enough political will can be built up to get past the perverse crony capitalism inside the health care industry, that's another question.
