My Sanders-supporting friends, let me put on my "older than dirt" political partisan cap and say this just once;
You stand at a crossroads now.
You can continue to strive for a more progressive Democratic Party in the future, for a lessening of corporate and wealthy interests within that party (tho if you think you're gonna get anywhere near "social democracy" in a European sense within the next century you've been huffing glue...). You can build grassroots organizations to help push the "Overton window" back to the Left.
Or you can retire to your tent to sulk about unfairness and corporate eeeeevil and stacked-deck primary processes. And as such you'll have as much effect on the political future of this nation as...Ralph Nader has had after 2000.
I've been there. I campaigned for John Anderson (remember him..?) back in 1980. I was a Dean partisan. I've labored for progressive candidates since I was old enough to vote. And I've been frustrated again and again watching "conservatives" work constantly and successfully within THEIR party to hijack it. Look around. The Donald isn't a "rogue Republican" - he's the Climax Teatard, the ultimate expression of what these Chrisopaths and antitaxers and Tenthers and Segregation Now - Segregation Forever diehard Dixiecrats have been drooling for since Reagan.
Since REAGAN; thirty-five years. Thirty-five YEARS, friends.
You want a "Sanders" in the White House and a Democratic version of the "Freedom Caucus" in the House? Are you prepared to work patiently for thirty-five years rather than throw a massive tantrum in this one?
Because that's what it'll take. And you can take those first steps today that will take us there then.
