That is really the only significant dirt that came from that leak. The Sanders stuff was overblown.

From what I've read, it appears the DNC directly violated their own bylaws by (strongly) preferring one candidate before the primary. Repeatedly and flagrantly.

If the DNC isn't even accountable to itself, how should American voters feel about them having control over the duopoly of private parties which are allowed to select presidential candidates? At best, their actions were revealed to be grossly unethical. At worst, criminal.

Most of the leaks showing the DNC "favoring" Clinton came after it was clear she was going to win the primary, and most of DNC wanted to focus on the general election. On top of that, individual staffers having a preference for the person they are very close to over the guy who joined the party just to run shouldn't be that surprising, but I haven't seen any evidence that it translated in substantial action to tilt the field in favor of Hillary. I'll concede the debate question issue was a bad look, but again, what advantage was conferred by telling the HRC team that a debate in Flint would feature a question about the Flint Water Crisis?

These sort of private discussion are totally reasonable for an organization like the DNC to have before the primary was 100% over cause they could see the writing on the wall. I didn't read every leak or anything like that but what I did see was mostly of this nature. This of course pissed off Sanders supporters (the point of the leak in the first place) but it really wasn't that bad imo.

The Brazile thing was though and I'm amazed she's not hiding in a cave somewhere in disgrace.

And the reason for that was because she was heavily pushed as the candidate by CNN, MSNBC, etc while the same media ignored Sanders. That it only became clear later that this media had relations with the Clinton campaign and DNC beyond just the personal biases of pundits is cause for concern IMO.
