This really sucks but the writing was on the wall for weeks due to her numbers constantly dropping. I was prepared for it for a while now but was hoping at least she could hold out until voting started. It didn't help at all that media coverage kept trying to erase her. When she's literally left off actual poll graphics in news coverage even though she's higher than others listed is 100% erasure by the media and that shit was happening for months. Especially back when she was peaking and in 3rd for a time. That's not to say that is only why her numbers dropped. I felt from the very beginning chasing at the groups Sanders and Warren were going after was a mistake. She like so many others believed he was stronger than he really was even when data showed he wasn't. Then attacking the person that was in part the favorite of a group she should have gone after and could have gotten was another big mistake. That I feel played a big part in why she peaked so early and never recovered.
