I implore people to watch 4 minutes of this (very long) video.
They make an honest criticism and case on what should be the upcoming strategy for Sanders -and his team- starting right now:
If the timestamp does not work, watch from 27:19 to 31:29
Essentially:
*Bernie and his coordinators need to start acting as the nominee. Seize Buttigieg latest strategy of "I'm the only sane/institutional person here, let's not fight among each others and focus on Trump".
*Switch the mood on the debates. Start openly inviting the rest of the candidates, to join him. Not pushing them, but giving the simplest argument: it's time, can't lose time on petty vendettas.
*Also, start turning back attacks from Bloomberg's camp to: Hey, if you really are serious on helping, start by doing xxx (like aiding the latino communities in Texas to register, etc)
*Have Sander's camp, start acting less reactionary online. No point in attacking the Beto's of the party, for old stuff. And instead have them start working for the cause.
*Start focusing more in Rural areas, putting forward proposals that he already have, but have not mentioned lately, like Rural hospitals. Buttigieg surpassed Bernie's effort on that front on Iowa; it can be done and will be needed.
I mean, sure: the establishment will try their darnest to stop his nomination. But his grassroot movement is already in motion. He needs to start changing the perception that he is against everyone, and try to press for unity.
If they still rebuke him, he at least can show the public that it wasn't because he was stubborn. Which will then put the onus on the top Democrats.
The remaining minutes are also interesting, because they talk about the new strategies Fox (and allegedly Trump) will start using against Sanders, where they will start twisting and attacking his integrity.
But the main points are contained in those 4 minutes. And I really believe it's Sander's best interest to pay attention to those ideas.
