The thing that bothers me the most about your rhetoric is that you can't even comprehend why Bernie supporters would be upset or surprised. America was beaten over the head every single day of Bernie's campaign with things like "He can never win, Hillary is inevitable" and "But ALL the super delegates already picked Hillary, he should quit". You're essentially saying that the tremendous institutional advantage Clinton had and the full backing of the DNC meant absolutely nothing. Even with all of this nonsense it was a very, very close race, and that doesn't even consider how many people were blocked from voting for not registering as a Democrat as far as 6 months in advance or the number of votes and voters that were simply purged.
Feel free to sit there smug because the corruption worked in your favor this time, but as an American you should be alarmed that it's happening at all. If this had been a fair election from the beginning I might, MIGHT have voted for Hillary. After all the **** that's happened the past 6 months, this coming out, and her VP pick, there is absolutely no chance I'll be doing that and she's going to lose a LOT of Sanders voters. Don't worry, I'm sure you'll be there to blame it all on Sanders voters when/if she loses to Trump, which is becoming more and more of a possibility.
It would maybe be OK that they did this if we had a vibrant multi-party system, but we don't. We have two and only two choices, and if those two private organizations are selecting the candidates for us our votes mean absolutely nothing.
