I think a candidate could benefit if they goaded their opponent into sucker punching on camera. Rather than going down, the victim would have to immediately look at the camera and point out that if its this easy for them to get under the opponents skin, imagine the opponent negotiating with foreign leaders.
That sounds ds good for a movie, but the effect isn't the same with unprepared cameramen and a bloody nose.
I don't really see a positive in this. Maybe if another candidate called your wife a whore, it might go over ok..?
