A person who meets the bullet-point description below is a person who is literally 180 degrees opposite every message Bernie sent this election season (except one; more later).

is corrupt

is (probably) a criminal

is a serial liar

supports the economic side (neoliberalism doesn't do it justice: it's neo-integralism on a global scale) of a fascist policy

supports and orders the death of men, women, and children abroad (as long as they aren't US citizens, and preferably also not white)

Bernie has said he'd support the Democratic nominee since the campaign started in 2015. So a candidate who fits that description wouldn't be the opposite of that message. However there is support and there is support. The real extent of his support for Hillary remains to be seen. My view is we should take Bernie at his word, though. He has endorsed Clinton, and he will campaign for her and other democrats. He has endorsed her in spite of her standing opposed to every issue he has advocated in this campaign because, as he himself has said, he thinks Trump will be worse. He may not think that only Hillary can beat Trump, but for whatever reasons he acts as if that is what he believes.

He isn't making some wink-and-nod gesture to supporters or asking us to read between the lines. He isn't secretly supporting independents and he isn't secretly preparing a third-pary or Independent bid post-convention. Could that change? Sure, but he will speak and signal plainly his intent to do so.

As exciting as his announcements for progressive organizations are, they should not be construed as pertaining to this election cycle. They are very clearly future-oriented. And, while some casual statements he has made indicate these organizations will support non-democrats "if appropriate," there isn't anything substantive to indicate what "appropriate" means or in what contexts (e.g. would that apply at all levels, including POTUS, or is there an "upper limit?"). We shouldn't assume intent or anything else, given how plainly and honestly Bernie has been to date, except where his actions can reasonably be interpreted (e.g. as is the case in his endorsement of Hillary over, say, Jill, in which we can reasonably conclude he thinks Hillary is the best candidate who has a chance to beat Trump).

Considering all this, I will make a controversial and antagonistic statement: Bernie ought to be considered a sheepdog for the Democratic Party, at least for now. This does not mean I think he has betrayed anybody. It is simply an observation of his actions and the conclusion I draw from considering them. So I will weigh his campaign rhetoric for this election cycle with a bit of extra skepticism that, in my opinion, carrying water for one of the corrupt criminal parties that run this country merits.
