I don't know, if you're hanging your hat that Hillary is corrupt, the email thing is more incompetence than anything. A lot of people have to deal with making sure their work product is confidential. Seeing an old person not pretending to even try to protect her shit is I think people are familiar with. Now, that doesn't mean she gets a pass on it, but if anything, that's more understandable.
The James Comey thing going "Uh, Hillary is under investigation, fuck I don't want to announce this" hurt her more because having the head of the FBI who is supposed to be neutral fuck you over like that was astounding at the time. Even then it may have turn what a blow out victory for Hillary into more of a toss up.
We didn't understand at the time just how much Hillary wasn't campaigning in battleground states until people started talking about it. That 2016 Hillary campaign was just a perfect storm of bad luck, undesirable events, and internal incompetence.
