Ah, if I only had a dollar for every time someone said "This [fill in the blank] is why Trump won."
I know why Trump won; it's no mystery.  
Trump won because he bamboozled a bunch of bottom feeders on the fringe, and lied and lied and lied to everyone else (personal-responsibility-shirking, low information voters who lapped it up) while demonizing a lone woman and turning her into the Scape Goat for All That Has Ever Gone Wrong Boogeyman (Wah! She is SO terrifying) and simultaneously screaming "The sky is falling! Run for your guns! The sky is falling! The White Man is being victimized! The sky is falling! Immigrants are the problem, The sky is falling!  We're all gonna die!!" scaring the crap out of people who were already afraid of their own shadows to begin with.  Meanwhile,  Trump sold himself as Superman ("I'll save you, Lois!"), swooping in to save the day.  
Doesn't seem like much of a hero now, huh? Just a big yellow con man who knows a sucker is born every minute, at least.
