Nobody has to 'admit' that Hillary is a crazy person. Everyone already knows that. It would be like finally admitting that O.J. is a Black man. We already know that.
The question the Dems are struggling with now, is what they can do to get her to SHUT-UP! and go away. The closer the Dems get to midterms, the more serious the situation gets. She is shooting friend and foe alike. She doesn't care.
They may call on the God of all Democrats (including Republican Democrats), the Darth Vader of Liberalism, George Soros to intervene and knock her out.
They have to get rid of her somehow, and the sooner the better. At this point, Hillary is damaged goods. She is a rotten apple in the middle of the barrel. She's spoiling everything.
