The question I have, does Bill want Hillary to win?
Great point. I hadn't thought of that. My guess is that he would not want Hillary to win. His ego couldn't handle it. The implication that she may be the reason he became President in the first place would be devastating to him and his legacy. The thought that her presidency could overshadow his is something he couldn't abide.
Can Hillary even become President? She has already served two terms as Co-President.
