The DNC fucked over Bernie.

The primary voters voted for Hillary over Bernie, even before the superdelegates became relevant at the convention.

Both can be true.

Regardless of all the shenanigans with the superdelegates, I highly doubt that the DNC would have nominated Hillary if Bernie had actually won the primaries.

Voters could have seen through the DNC shenanigans and chose Bernie, but they didn't.

It's the same with all the dark money corporate contributions... Does it influence the result? The data surely shows that it does, but voters still have the choice to NOT let that dark money spending influence their decision.

All of that stuff in the book was more or less out in the open and publicity known during the primary campaign. Leftists and progressives could have registered to vote in the primary, and if they had none of the fuckery would have amounted to anything. But they didn't and Hillary got nearly double the votes Bernie did. Also Bernie isn't a democrat, everybody ignores this, of course the democratic party would favor an actual democrat for their nomination, but I digress. If leftists and progressives actually voted he'd have won, but they didn't, and it wasn't remotely close.
