See, this is why it's so difficult attempting to have civil discourse with you. You dodge the issues until the last. We know the primary was rigged to oust Bernie. We know questions were given to Hillary in advance of debates (the fact that questions were leaked to Hillary automatically makes her corrupt in this case since she had to know the questions were leaked).
Well, regardless of whether or not you can see any connection, the vast majority of Americans (inclusive of many, many Bernie supporters) certainly believed Clinton was part of the "fix". So whether or not she actually knew anything about it (as you say, there is no proof tying her, specifically, to it) voters believed she did. And honestly, that's all that mattered. They voted accordingly.
