If you you look long enough at a bad situation you will usually be able to find something good that will result from it. I guess that is the case for Bernie Sanders' campaign. Even though he turns out out rabid 'Sandernistas' on social media that will attack anyone that even questions his dogma he will not be the winner of the democratic nomination. Is that a bad thing? Yes, it demonstrates how dysfunctional our democracy is in America. Is there something good about it? Yes, Bernie has shown himself to be surrounded by less than competent people and the fact that he is vulnerable to their bad advice and actions demonstrates that you don't want him and his 'Sandernistas' as leaders of the free world.
Even though he later said that is was a mistake by a low level staffer here is what happened when someone had the audacity to have a sign that raised a question at a Bernie rally:
But staffers working for a candidate widely viewed as one of the most progressive members of the Senate were apparently not happy. Security was made aware of a threat: Some students who support Sanders were holding a sign with a question on it. A tactic right out of the Bush campaign “playbook” went into action.
“They told us to either put the sign away or leave,” said Sana Hashmani, one of the student activists. “We asked why, and they said that Bernie’s campaign staff had said the sign had to go.”
And if you think that it was just the 'low level staffer' that has a problem understanding dissent then listen to how Bernie handled the Palestinian question at one of his events. https://youtu.be/Vf2cCdgwgoM
After seeing how he handled the issue there I will not be voting for him.
