"The current model and strategy of the Sanders wing of the Democratic party is an absolute failure."

30. That sounds very much like

all the people who are saying that Hillary should sit down and shut up. Bernie can write two books and run around promoting them, but the woman has to shut up. Bernie supporters want us to shut up and not criticize their patron saint.

It is valid to criticize Bernie for his current comments and actions. He is not being told by the OP to shut up, simply to change his words. I don't think he will do it. He is getting too much attention this way. If anything, the OP could have added that Bernie should be saying a whole lot about the Russia investigation. He isn't.

We are focusing on beating the GOP in 2018 and 2020. I see a lot of candidate training and activism. That is very positive.

I don't like it that the activism coming from Bernie supporters and his Our Revolution group includes primarying Democrats and possibly supporting repubbies. The only one who should be primaried is Bernie. I hope he has a strong Democratic contender. Of course if he changes his words and activities, I could change my mind on that. But I don't see it happening.

I agree with the OP. And if it is all right to criticize other Democrats here, people like Pelosi and Booker, then there should be nothing wrong with criticizing Bernie.
