With regards to Bush and Kasich, it absolutely baffles me that neither of them have had anyone talk to them about posture and body language. Both of them hunch their neck over and slouch (except Bush when he's standing on his tip toes) which make them look tired and weak and Kasich in that interview has his hands on his hips making him look like he's pissed and ready to jump down the interviewer's throat. These are minor, elementary points like stand up straight, have open body language, and don't fidget and yet, seemingly, no one has told them about this issue or they just don't listen. It's such an unforced error because it contributes to the subconscious image people make of these people and when the man you are trying to beat happens to be a 6'2" bully, anything you do to make you look smaller or nervous comes across TERRIBLY.
