I'm not a 'yuge' fan of Hillary, mainly because we've already had a Clinton in the White House, but probably 80% of her bad opinion rating is due to years of repetitive character assassination rather than actual misdeeds, maladminstration, or incompetence. John Boehner went a long way toward admitting this in public.
Donald, OTOH is genuinely malodorous, incompetent and nasty. I would not be astonished if he is into senescence due to his overuse of superlatives and underuse of standard English grade school vocabulary.

There is some argument to the fact that he is less likely to reach 'the button' on account of his tiny hands, but I think this is an exaggeration.
