It took me some days to digest the NY primary but now I regrouped emotionally and would like to share some thoughts.

A view about what happened:

(1) The NY primary was stolen by voter suppression and, possibly, by fraud.

(2) The 'business model' of the Democratic establishment is not much different from the one of the Republican establishment. It is a machiavellian model which relies on propaganda, voter suppression and fraud.

(3) The USA is not a democratic country anymore, but an oligarchy ruled by the 1%, the Dem/Rep establishment, and corporate media.

(4) The masks have fallen, (1), (2), (3) is apparent to millions of people.

(5) The people who are not prepared to accept (1), (2), (3) cannot be isolated and silenced anymore, they are interconnected via the internet and are capable of joint action.

What I suppose Bernie's view is:

(a) I suppose Bernie agrees to (1)- (5); he considered to run as an Independent but I suppose he thought it would be easier for the oligarchy to marginalize him by using propaganda, voter suppression and fraud, and that's why he ran as a Democrat.

(b) I suppose he is convinced that NY was stolen (have you noticed that he did not appear disappointed but angry in his recent speeches ?), but I suppose he might think that accusing the DNC and HRC of election fraud without clear evidence would lead to an escalation that might end up in mass protests and the use of police/national guard violence against Bernie supporters (remember Occupy). The corporate media would then blame Bernie for the violence. I suppose Bernie thinks that we should not choose this type of battle (at least not now, and not without clear evidence of election fraud).

(c) I suppose Bernie wants to re-democratize the USA, by creating an increasingly powerful progressive movement inside and outside the Democratic party that would elect as much real progressives as possible and demand that progressive positions are endorsed and implemented by Dem elected officials (or threaten them with challenges in primaries). For me this medium-term strategy makes sense because the Dem establishment's masks have fallen and the establishment will become increasingly unpopular. Furthermore, in the future more and more critical young voters will replace corporate-media-informed voters.

What I think we should do:

(i) Most important: We help Bernie to win as much primaries/delegates as possible - starting NOW by phonebanking & canvassing for the next primaries - in order to strengthen his position as a movement leader (crucial when negotiating with the Dem establishment at the convention) and retain his chances to become the Dem nominee, either by winning yuge in California/Oregon, or by other unexpected developments (e.g. E-mail server, evidence for election fraud + a connection to HRC)

(ii) We increase our movement by building/expanding an progressive infrastructure of interconnected websites, platforms, social media forums etc. which can compete with the corporate media; we need to be be resilient against paid Brock-trolls while developing a participative type of community that will motivate people to join our movement.

(iii) We develop ways of monitoring elections and ways of exposing all kinds of voter suppression/ fraud attempts.

(iv) We help to elect as much real progressives as possible; some of us might want to consider to become actively involved in politics.
