I agree for the most part, the way Hillary is impacted how she allowed a member of her staff to have those emails to begin with and whether that was good judgment.
again, a lot of these documents weren't "classified" until someone looked at them years after the fact, and decided they didn't want these discussed publically.
Hillary has asked repeatedly to declassify these documents so we can make our own judgments on them.
The problem with this investigation is that we are being asked to take a lot on faith that
1) These Emails really had super-secret stuff in them
2) That Hillary should have known they had super secret stuff in them
3) That someone might have seen them who shouldn't have.
