Its an astonishing failure from her and her campaign team and is because she has focused on anti Trump rather than articulate why her presidency would be better for all Americans, republicans included.
She has basically answered the wrong question.
Its BrExit all over again.
Regardless of what questions she is answering, the Wikileaks emails show her, the Clinton foundation and the entire DNC as being massively corrupt.
She has only herself to blame for Trumps resurgence.
