JUST WATCH THE SCREEN.
HE IS YOUR PRESIDENT.
Off camera the candidates' facial and micro expressions - detailing how they actually feel - is missed by the audience.
The mouth may utter one thing...the face another.
However, when live images of the face, forehead, eye and lip movements, nostrils flaring, a dismissive attitute, are captured by the camera, a much deeper understanding of the candidate is made possible.
You be the judge.
