This image of Ted Cruz was captured on 16 January 2016 in Myrtle Beach, South Carolina at a Tea Party event. Senator Cruz's facial expression in this moment is displaying what is known as a "Lateral Lip Purse". It's crucial to not confuse this with a "Forward Lip Purse". Although there are nonverbal modifiers which, if coexisting, will alter its meaning, when the rest of the face is neutrally configured, the lateral lip purse is indicative of an, open (non-secretive) decision making thought-emotion.
This particular expression is very prevalent in restaurants as people peruse their menus'.
