Now, in 2016, I have seen many complaints during the Clinton/Sanders contest about how the DNC has treated Sanders unfairly. There have been irregularities, but nothing to the degree of what happened in 2008 and nothing tied to the Clinton campaign now which could be directly tied to the Obama campaign then.
Here's the bottom line: Hillary Clinton should have been the Democratic nominee in 2008. She won the popular vote - that's how it should work. Sanders supporters are rightly justified in complaining about an overly complicated and "rigged" system, but do themselves no good by placing all of the blame on Hillary Clinton, who was a victim of this very system only eight years ago!
And let's face it: Hillary Clinton is winning the popular vote in the 2016 primaries. To maintain this lead given by common registered Democrats is to be the legitimate Democratic nominee for President. Obama could not claim this legitimacy in 2008 as the DNC handed the nomination to him. It is my hope that Sanders does not become Obama. As much as I like Sanders and wanted him to win the nomination, I can not abide a cheater. I would hope that Sanders agrees with me.
Your vote is your own. If you don't like the nominee, you don't have to vote for the nominee. Speaking only for myself, I am at peace with voting for Hillary Clinton in the general election despite voting for Bernie Sanders in the primary because she has run as clean of a campaign as possible within the constraints of a very flawed and irregular system. In the future, my hope is that we always look to the will of the people and away from the machinations of the establishment elites.
