... But if the DNC and Democratic Establishment cannot figure out a way to cheat Sanders out of the Nomination again ...
... The Donald will be a one-Term President ...
Your best chance is that Pelosi, Schumer, Obama, Clinton (aka Dem. Leadership) get their act together, aided with Bloomberg's Billions, and find a way to keep Trump in Office by somehow cheating Bernie. They have already made (the obvious) clear, which is that they would happily take another four Years of Trump rather than lose their Power, Position and Privilege to a Sanders' victory.
So anyway, I wish you guys Luck, but ..... I don't like your Chances .....
Trump's lock on the nationwide Anti-Establishment movement will disappear if the Dems cannot find a way to Stop Sanders and ... God forbid he choose Tulsi as his running mate ... it would be Over - nothing Trump can do in the next 8 months could overcome his failure to deliver on his promise to save the wasted Trillions on pointless foreign Wars, which could fund Bernie's programs to help American families ....
But there's still a chance - it's still possible that Pelosi, Schumer, Obama, Clinton et al. will pull it out for you - they are expert cheaters after all, and they're solidly in your Corner - they probably want Trump to win as much or more than you do ....
And you also have CNN and MSNBC in your corner - though that's probably a liability, except they'll do their best to give cover to any cheating maneuvers.
So anyway, like I said - best of luck to you - don't give up yet - there's still some chance ....
