Correct, she doesn't get involved in the back and forth, point counter-point arguments with skilled and trained negotiators.  

She holds authority and responsibility over the entire process and will authorise concessions or additions.  She writes the check and needs to agree with direction or items.

She is ultimately not given credit when negotiations succeed, that's given to the negotiation team, but she sure is to be held responsible for its failure.

Why wont you hold her accountable for the failure of her project?  If it succeeded would you be giving her the credit?

The irony of your hyper-partisan blinders accusation is a bit rich, there pot.  Meet kettle.
