I was going from memory of articles that I read. I'm not going to look it all up again, I'm afraid. I am looking to be positive and that means not getting in an argument about details that I'm already satisfied with. What I do know from a quick effort to find those exact articles again for you is this: the people who were not accepted were not democrats. They knew the rules of this event. They should have been well-coached by the Sanders campaign. I would HOPE Sanders' people would work hard at this, wouldn't you?
They were not registered for the convention as Democrats.
I applauded Sanders for applying to run as a Dem. He said it was because he had a better chance using Dem rules/systems than using his own independent system. He said in September that it was because he wanted the left united behind his ideas and did not want to risk a GOP win. So he ran with the Dems to make one unified left position. He felt he had a chance to be that winner.
I agreed with him. I thought he did have a chance. I personally felt I couldn't lose because if he got the nomination, great, and if he didn't, his campaign would move whoever did win to the left.
He had that going for a while and now he is fucking that up. Alas. He decided, it seems, to "go for broke;" meaning he wants the win only and is willing to risk losing ALL the socialist momentum in pursuing it.

I'm not that much of a risk-taker when the stakes are this high. And at the beginning of the campaign, he said he was not, either.
Meanwhile, none of the rules that he signed on for have changed since the day he CHOSE to use this method.
And so many of his supporters are now ANGRY over the rules he chose to sign up for.

He should correct them and remind them why he CHOSE to run as a Dem within the Dem rules.
If there were no Superdelegates, we don't know that Bernie would have done well. Others might have run - maybe even Trump as a Dem. It's what happened to the GOP. They got someone that NO one in the party likes.
I see that you did not respond to other points there in my post and I'd like to know why.
Because it's a morass of directionless rage. That's YOUR way of doing politics, not mine. Have fun at it, I don't wish to play. People have been making wildly stupid comments about those of us who _supported_ Sanders and now that we are saying, "hey, I'm not thinking the current direction will work!" y'all are flinging poop and saying we love Hillary and her supporters are just as bad, blah blah blah.
And I don't want to play a game where I say A and you claim I said B. I'm discussing things, calmly, enjoying my coffee and you appear to be spewing froth. So have fun with that, I don't need to answer.
Bottom line for me:
Sanders signed up to play this game with these people. So shut up and play. He has good ideas that need the Dem party to get anywhere. So let's do that.
He's harming what I supported by this whingeing against the Dem party instead of just staying on message and remembering that the GOP is the real concern. Advancing his ideas instead of himself. He ideas could have won, and would definitely have changed the Dem direction. Now I'm not so sure he can.
There are no "buts" about those death threats and I'm disappointed that he did not condemn them thoroughly and without hedging. That's not who I thought he was.

You wanna come and join the Dem System without joining the Dem party? Sounds like you don't want to be seated as a delegate to the Dem convention, sounds like you don't want the Dem nomination.
Which makes me mad because I wanted these ideas in it as adult ideas, not have them driven off for being childish.
