Hillary is looking at the camera well in front of tRump.
Obama reads a lot, probably with glasses, and is accustomed to looking through the bottom of his lenses. Without glasses he tips his head back.

"There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
-- Isaac Asimov
