Many people cited her "emails" as a reason not to vote for her, but I heard few elaborations about why exactly they did so. I understand the argument about her mishandled of classified info, could've endangered national security, very stupid and careless. But it was chalked up to, essentially, the fact that she was tech illiterate (older generation), didn't know how email systems worked.
On the Podesta email hack and leaks, what can anybody name specifically from those emails that was damaging in any way? I never saw reporting on the content of the hack, few Americans knew/know what are in them, and tbh idk what's in them but I'd bet they're mostly innocuous behind-the-scenes stuff (what you would expect from the emails of a campaign chairman).
Her age and tech illiteracy do not explain her lying multiple times (i.e., the private server was purely for personal emails such as her daily routines and correspondences with friends) or having her staff delete 30,000 e-mails. The scandal was both about national security and her habitual lying and corruption. It simply confirmed what many Americans don't like about her.
