The fact that she feels the need to despite the fact that she's clearly still winning easily and this can only damage the party in the long run should convince anyone that she is a terrible politician.
If any more mainstream good candidate had run, I'm confident she would have lost.
Wah wah wah. "Why is she going to do to my candidate what he's been doing to her all along?" The knife cuts both ways. All's fair in love and politics. Sounds like the Sandernistas are starting to get nervous now. Maybe they realize their train is about out of steam.
This is bad politics. You'd easily realize it if you weren't such a deluded hack.
