I agree with what you are saying here. She has had coughing spells she cannot shake. One thing, her body language does not display confidence. The powers behind the scene do not want to lose the power to control the Office. They do not want drastic change in policies. The media doesn’t even want to shake anything up. They all seem happy with the system as it is. The first word I think to describe it is lackadaisical. Keep the country bored and tired and in an hypnotic state.
Is her behavior really that much different from how she was years ago? I don’t recall an animated, robust speech from Hillary - ever. Just tears or robot/drone; I would not be surprised if she ended a speech with, “Bueller, Bueller?”
