Then why did it matter if the party adopted his platform in 2016? If he’s the only one who can be trusted to fight for it, then why insist that the party promise to fight for it without him?
A) Because a large chunk of the party HAS moved to the left on various levels of government local and national. Because it was important to show the masses that those policies could be popular outside of tiny bubbles in urban areas. That doesn't mean the donors that run the party aren't gonna run a couple candidates who job it is to reign things back in (much like the media has spent the past 3 years successful deflecting blame onto Russia instead of analyzing what went wrong and what needs to be reformed).
Again, both Woob_Woob and I have indicated that we really like Warren and trust her and would vote for her. I don't quite trust Harris because I watched her rise within CA and have close friends whose career is to run campaigns (one of whom I will mention later) who have made it clear how easy her move up the chain of command was (particularly over Loretta Lynch) as the chosen one. Yet I will vote for her if she is the nominee specifically because she has held firm thus far on Bernie's platform.
B) The primary was rigged. I could give you a laundry list of things that happened in Nevada leading up the caucuses (but I'd have to hit up my homie who has a better memory than I and who was down there the whole time). The one example that comes immediately to mind is the fact that The DNC had said that caucus locations had to be set in stone 2 weeks prior so that campaigns had time to get locations out to their supporters. Seems fair right? Except what happened was that I'm out at like 4:30, 5 in the morning putting door hangers up that have causes addresses on them and get a phone call: the caucus location has been switched up THE MORNING OF. And it happened all over the state. So now, the thousands of volunteers have poured their energy into passing out incorrect information. Later that evening as were all getting drunk and grieving over a close loss, somebody shows up with a Clinton hanger... and guess what- IT HAD THE CORRECT ADDRESS. Now can I confirm that Clinton had the correct info on all of her hangers for caucus locations that had been switched? Obviously not, but I can extrapolate.
When you have things like that happening on the ground level and Bernie's super volunteers (many of who are people who have been drawn into the process for the first time) are seeing stuff like this, how do you think that makes them feel about our political process or the DNC? Meanwhile, the media is reporting on none of it and Bernie supporters are being called conspiracy theorists for months (for sharing these type of stories on places like Reddit)... until the DNC emails dropped and the cat was officially out of the bag.
C) That said, the recent quote from Bernie about the 2016 being rigged was completely taken out of context and was the media successfully baiting him. Bernie fucked up. I think Bernie's biggest flaw (and the one place where he actually does get grumpy) is that he sometimes allows the media to get under his skin because he feels like he is held to a different standard. See his answer on guns for an other example.
In the case (I think) you are referencing... the talking head said something like "will you drop out if you lose" and he said "we plan on winning" and then she said will you drop out and "will you drop out" and he "we plan on winning"... then she said "some people think you cost Dems the election by staying in the race to long". Which is a talking point the media loves (and I will continue the conversation on below). Because of this Bernie got snippity and said "and some people say I would have beaten Trump if the race hadn't been rigged against me". Do I think it could have been handled better by Bernie? Yes? Do I think the media's goal is to bait with with no win questions that can be turned into a headline? Absolutely. But considering all the stuff I mention in point B and the fact that the media is engaged in non-stop hit pieces on him, I also understand it and think that anybody capable of critical thinking should be able to read between the lines. I have heard him say that we need to get behind the eventually nominee AT A RALLY in Los Angeles on March 23rd (I remember the date because it's my birthday). So yeah, which moment do you think says more about his intent? A moment with a talking head or Bernie talking directly to his core base?
D) I wish Bernie's closing statement had been prefaced with a "thanks to everyone on stage who has moved to my side of the policy debate". And I think most of his supporters do. He has to adjust to 2020. I also think (and I was with activists last night who actually know his hires and said as much) that he needs to fire his communications director ASAP. That said, what he said is inherent to what people like Woobs and I believe. That no change will happen so long as a candidate is taking Super Pac money. Specifically from Wall Street or Fossil Fuels. Because of Trump's fundraising, personal weath and the industries that get behind him-- I'm okay with money being taken from other places (in the general election) for this one go-round. But if you are talking money from Wall Street or Fossil Fuels than you have just become compromised in your ability to systemically fight this countries two biggest issues: economic inequality and climate change. And I think that's what people like myself use as the gauge for whether we can trust you: who are you taking money from? And I think that was Bernie's message... is not that nobody on that stage can be trusted-- but that he CAN be trusted.
I also think there is a ton of hypocrisy in your stance "That’s brinkmanship, not statesmanship" and "he fractured the party". No, the DNC fractured the party by blatantly tipping the scales AND THEN ARGUING IN COURT that they had the right to do so. Furthermore, brinkmanship is exactly what the Clinton's were known for. It's how they functioned. It's why I don't blame Warren from refraining in an endorsement of Bernie (where as some of his newer-to-the-process base do). Because I understand that by staying out of it until it was clear it was over = an endorsement for Bernie under those circumstances. She knew damn well that she would have no voice with Clinton if she did endorse Bernie and he lost. Furthermore, Bernie was never, ever going to have sway over the direction of the party under Clinton unless he played it as he did.
I'd add that no matter what the media tells you, it wasn't over until after CA. Bernie's organizers built their WHOLE operation around forcing a contested convention by stealing delegates in rural areas and closing the delegate count even as they were losing the popular vote in urban areas. And while the day that Ohio, Missouri, Pennsylvania, ext voted was the day it was clear he was probably going to lose, it wasn't 100% clear he was going to lose until after CA. Which is why Warren endorsed promptly there after.
E) The guy I was with last night ran Bernie's volunteer program in several key states. He is a Latino that grew up in the heart of Los Angeles. He is a very successful field organizer who was in the middle of running a campaign and got the blessing from said candidate to drop what he was doing and drive down to Nevada and work for Bernie. Last night he showed me a CSPAN video that he saw as a 10 year old kid while his mom was watching TV and his surrounding neighborhoods could be seen burning in the distance from the riots. It's the video that inspired his interest in politics and the reason he dropped everything he was doing (at a pivital point in his career) to go work for Bernie:
