Except for a few people who had to quit their jobs and clear favoritism from the DNC chief which is supposed to be neutral:

The RNC had a similar anti-Trump preference. There's similarly no evidence they rigged anything against him.
While there may not be proof that the DNC rigged it against Sanders, that doesn't prove it wasn't rigged. It only proves that no evidence has come to light that it was rigged.
That's simply false. The accusations against the DNC of "rigging" primarily revolve around bias (revealed in the email dumps), not actual electoral fraud. The RNC was almost certainly biased in a similar (likely more intense) manner against Trump.
It's also entirely possible to rig an election unsuccessfully.
And yet Trump has accused the RNC process of being rigged many times. Strange how the current narrative seems to be that only the DNC is exceptionally corrupt, to the point of rigging an election, and possibly having Seth Rich killed as if the Democratic party was literally a crime syndicate.
There really isn't proof of anything, either way, other than "rigged elections" being the current political accusation du jour.
That is all that anyone is really arguing here, contrary to this assertion:
