That claim is false. Either you agree that the claim was false or you are a liar.
You are trying to change the subject--which is apparently what people do nowadays when they are caught in a lie, and that has contributed to this environment of fake news and information. Yes or no, did Hillary win the primary popular vote?
The only correct answer is YES--and thus the post by Hylandr was a LIE. Those are facts--absolutely irrefutable facts. I'm not going to debate them because they are not debatable.
Once we've established that incontrovertible fact--we can move on to discussing whether the primary was stacked against Bernie. IMO, yes--it was, just like it was stacked against Barack Obama in 2008. But Obama was a far better candidate with far broader appeal and he overcame the establishment bias. Bernie fought a valiant fight but fell short. In hindsight, I wish I had voted for him and I wish he had won. Not because I think he would have been a better president (I agreed more with Hillary's positions, I think she's smarter, more pragmatic, more experienced and harder working) but it really does look like Bernie would have had a better shot against Trump based on how the general election turned out.
