Bernie Sanders isn’t getting all of the endorsements that he and his campaign think he should be getting.

The Service Employees International Union’s signature campaign is Fight for $15, and yet they endorsed Hillary Clinton despite the fact that it is Sanders, not her, who supports a $15 minimum wage.

Most of the 46 members of the Congressional Black Caucus have endorsed Clinton despite the fact that Sanders can make a case that his criminal and economic justice platforms are better for the black community.

Yesterday, the Human Rights Campaign endorsed Clinton, and while Sanders hasn’t exactly been a leader on LGBT issues, at least he hasn’t tried to airbrush past support for the Defense of Marriage Act.

Of course, there’s a simple explanation for why Clinton is winning these endorsements and Sanders isn’t: These organizations think Clinton is going to win. Two particular endorsements, however, seem to have gotten under Sanders’s skin. Last night, he lashed out, claiming that Planned Parenthood (which endorsed Clinton earlier this month) and the Human Rights Campaign didn’t endorse him, at least in part, because they’re part of the “political establishment” that he’s been “taking on.” Said Sanders:

What we are doing in this campaign — and it just blows my mind every day, because I see it clearly, we’re taking on not only Wall Street and the economic establishment, we’re taking on the political establishment. And so I have friends and supporters in the Human Rights Fund, in Planned Parenthood. But you know what, Hillary Clinton has been around there for a very, very long time and some of these groups are, in fact, part of the establishment.

Look, there is a case to be made that the Human Rights Campaign and, to a lesser extent, Planned Parenthood are part of the progressive “establishment” in that they have the ear of Democrats in Congress and make high-profile endorsements. They raise money, keep offices in Washington and lobby Democrats on the progressive side of their respective issues. Many of Hillary Clinton’s supporters reacted strongly to the word “establishment” as if both of these organizations are completely outsider. I wouldn’t go that far.

However, at most, these organizations are a very different kind of “establishment” than what Sanders invokes when he talks about Wall Street and the economic establishment. Wall Street and the economic establishment are what they are because they have captured both parties, not one, and have done so to such an extent that most of their influence has been won before they write their first check. Practically everyone in both parties already agrees with them on core economic issues. They never bother to endorse candidates because they don’t need to; no matter who wins, they’re on the same team.

One of Sanders’s overarching themes in his campaign is a critique of the neoliberal economic consensus that politicians in both parties have agreed to and the financial sector helps enforce — a consensus that he doesn’t feel any other candidate in either party would think to criticize, let alone do so adequately. This critique can’t (or at least shouldn’t) apply to Democratic constituencies and advocacy groups because, well, Sanders really doesn’t disagree with them on much. Extending the word “establishment” to them in such a way implies the same kind of shady influence peddling for the sake of maintaining the status quo at the expense of the general public that we mean when we say “Wall Street establishment.” That’s not even close to fair to apply to the Human Rights Campaign and Planned Parenthood.

Sanders basically just equated the these progressive advocacy organizations — organizations with which Sanders has practically no political differences with — with Goldman Sachs. That’s bizarre. There are better explanations for why he didn’t get their endorsements, and he knows it.

I like Bernie, but I’d also like him to walk this one back.
