“Democrats,” according to Sam Stein, have found “a universally agreed upon culprit for [Elizabeth Warren’s] stall in the polls: her embrace and handling of Medicare for All.” Or perhaps that’s putting it a little strong, since six paragraphs in we find out this has merely “become the topic of intense debate in Democratic circles.” But either way, we know that at least four people think Warrencare has tanked her campaign:

• former Harry Reid staffer Adam Jentleson;

• Biden spokesman TJ Ducklo;

• an anonymous aide to another one of Warren’s opponents; and

• a “senior Democratic Party member” (whatever that means)

I’m not sure why it’s news that two professional opponents of Medicare for All — along with (for all we know) your aging Blue Dog grandpa — think that it’s a political liability for Warren; but let me propose an alternative explanation.
