Trump makes a good point. One thing that can now be said with certainty about Clinton is that she has no desire to unite the country, and indeed "deplores" almost half of it, with no desire, it can be fairly said, to associate with, listen to or empathize with almost half of it.
Trump's been accused of hating lots of Americans too, but at least that's the projections of others, not Trump's own words. Clinton has admitted her bigotry with her own words - almost half of us are dead to her.
