Reality: Debbie Wasserman-Schultz resigns because she most certainly put her thumb on the scales for Clinton in the primaries.
Reality: Her replacement, Donna Brazile, is fired from her position at CNN because she tipped Clinton off with a question to be asked at an upcoming debate. Asked about what she would do differently, rather than say, 'refrain from cheating,' she instead mentions better internet security.
Reality: Brad Marshall, DNC Financial Chief says in an email, “It might [make] no difference, but for KY and WVA can we get someone to ask his belief...Does he believe in a God? He had skated on saying he has a Jewish heritage. I think I read he is an atheist. This could make several points difference with my peeps. My Southern Baptist peeps would draw a big difference between a Jew and an atheist.”
I don't think Bernie was cheated out of the nomination, but I know for a fact that the supposedly neutral DNC favored Hilary Clinton. I know for a fact that Hilary has never risen after initial polling in any of the campaigns she's run--she's only dropped. I know for a fact that she was the second most disliked person to ever run for President in the era of reliable polling. I know for a fact that she lost to a reality TV star.
I will believe until proven wrong, that the Democrats are clinging to the Putin/Russia/hacking malarkey to explain away the 2016 results. If they don't, big donors are less likely to pony up in support of total incompetence and ineffectuality.
