The history of Presidential debates, and really any political debates between candidates, has been shown to declare victory more based on body language, and the way answers are given, than what is actually stated by the candidates!
It has been said that the eyes are the “windows of the soul”, and they do, indeed, reveal a lot about a candidate, and really about anyone one meets and deals with in life.
Visual cues really tell us a lot, including type of hand movements; whether someone is nervous or jittery; the tone of voice; whether anger or emotion show through, whether someone comes across as genuine and caring; and a sense of compassion and humanity.
Going by this reality, Richard Nixon in 1960 and George H. W. Bush in 1992 were harmed by visual cues a great deal, and they both lost their elections, even though it could be argued that both were better qualified than John F. Kennedy and Bill Clinton!
This is something to keep in mind as one watches the Obama-Romney debates, and the Biden-Ryan debate, over the next few weeks!
