The fact this is two years old doesn't make it any less interesting. After she shakes hands with the moderator, why does she insist on walking over to his side of the stage before going down to the crowd? Is it just a coincidence? Why Didn’t Trump & Clinton Shake Hands At The Last Presidential Debate? She crossed his side of the stage to make him think, for a split second, that she might have been coming to shake his hand. Someone in his position might therefore get ready to walk over towards her. If he followed after her, he'd eventually realise "oh, she wasn't coming for me". Having realised this, someone in his position would either have to stop walking towards her (as her back would now be turned), and thereby look a bit clumsy and undecided. Just look at the way she crosses over and does her little fake wave, and various other taught body language mannerisms.
