How could a private organization violating their charter extend to criminality? 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?
