#BernieOrBust is the equivalent of crying in the corner if you don't get your way. I wish Bernie supporters who do feel this way would just be intellectually honest and say #BernieOrTrump or #BernieOrKlein.
No one else has earned my support yet other than Bernie. Being a party mook is nothing to be proud of. When she was campaigning for Barry Goldwater, Bernie was getting arrested protesting for civil rights. Hillary has not earned the win anyway, it's all based on superdelegates whom many declared their support before a single vote was cast. That's anointment not election. She's feeling the Bern I assure you, or will be soon because she has an enthusiasm gap outside of Wall Street. I wouldn't work for Hillary's campaign even if they did pay me. Dirty money as far as I'm concerned.
And I don't see what you mean by #BernieOrBust being intellectually dishonest, can you explain? There is so little substantive difference between Trump and Clinton, that I completely understand how Sanders supporters feel that way.
