For their behind closed door conduct? Yes... act on that information how you will.

For getting hacked? No (other than judging the technical team competency).

Same applies here.

Do remember though that the RNC was also hacked at the same time as the DNC, but only one was released right before the election.

That doesn't seem comparable. The DNC and RNC were hacked by different actors.

My point was that this news is of the hack, and not of bombshell revelations from the emails themselves, which kind of indicates there's nothing there.

If you found the smoking gun, you would say "look I found a smoking gun!".
