Earlier today Donald Trump was caught on camera spying on Melania as they both were voting in Manhattan.
Note that Trump's eyelids are partially (mostly) closed with his head and neck simultaneously tilting backward (0:31 - 0:32). This demonstrates an attempt to act in a clandestine manner.
Intriguingly, a split second later also pulls back further - as his head-neck-torso repels away from his wife - indicating either that he (of course) doesn't want to be caught - but also telegraphing (to those who are looking) that he does not like what he's seeing.
A second later (0:33) as Melania looks over at him, Trump's upper body quickly moves back in her direction as he displays a "Rationalization Rapport Empathy Expression" (aka R2E2). In this context an R2E2 is strongly suggestive of an attempt to cover for deception and clandestine behavior.
If we rewind back two - three seconds (0:30 - 0:31) we see Donald Trump's first attempt at stealth. Here there's another nonverbal clue - his prolonged lateral thrusting of his jaw (here to his right). Clustered with his coexistent secret glancing, this lateral jaw movement is profound signal of low confidence and distrust.
Take Home Point: Donald Trump distrusts Melania and has diminished confidence she will vote for him.
