I assume you are quibbling over the semantics of the word "rigged"?
Mmmmmmkay. The dnc worked hard to favor hillary and get her nominated. She won, but it was very close. It is far from a stretch to claim she wouldn't have won without them. The evidence of what happened resulted in the quick resignation of dws after a brief struggle.
Afa as evidence, google it. It's there. No one would provide a single example of Trump being a racist when I asked multiple times, for obvious reasons, so I'll let you do the work.
The dnc wanted hillary badly and did what they could to help "rig" the election. Whether they are responsible for the outcome is hard to prove or disprove.
