Wrinkled nose of Hucakbee of KY clerk shows "bad smell" of Supreme Court ruling as far as he's concerned.
An almost wild array of hand gestures from Kasich.
So often the inner eyebrows arch up for Cruz, a sigh of anxiety, surprise but also sadness. Disappointed in how others react, contrary to his own instincts, in political situations?
Lower eyebrows and narrowed eyes of Huckabee show sense of need to resist, one of the key meanings of anger.
Interesting how often Paul looks down in closing answers, almost a bit withdrawn.
Very tight facial expressions from Kasich, seems uptight guy.
