I still don’t quite understand why Hillary was disliked so much.
Eh. I voted for her but she was just bland. That's enough reason.
But several more I can think of
1. Her being an outspoken women who came off as "entitled/proud" rubbed some people the wrong way
2. Benghazi was unfairly weaponized against her
3. The shenanigans with Bernie really pissed off some on the left.
I'm sure there are more reasons. Most aren't valid. All things considered, she was relatively likeable up to the end of her stint as SoS under Obama. The turnaround into casting her as the nasty lady was unfair. But she didn't help matters herself.
