I agree that there are trends at work but many of the criticisms of her were only apparent in the last few months so saying that the DNC and democrats in general should've known somehow that she wasn't a good candidate and that their picking of leadership was fundamentally flawed seems odd to me.

Maybe if she had divorced and denounced Bill before the campaign run... They were not exactly free of scandal when Bill was in office. Her secretary of state term was... memorable. The situation was only unpredictable to maybe the youngest Millennials.

She was pretty unfazed by most of those scandals in the end, though. I think part of the reason they liked her is because she has been through so many scandals and was still the political force that she was. In the end they were wrong but a year ago it wasn't that unreasonable.
