I realize this is the far left wing "party line" -- especially as used to keep the black voters in line, but frankly I'm surprised you are regurgitating such ignorant nonsense. You have always seems more intelligent that that.
Try this, Trump won because:
1. He ran against a hateful criminal whose entire personality drips with insincerity and distain toward anyone outsider her own social circle that is so obvious she may as well wear a sign around her neck that says "If you're not from the New York-Washington corridor or California, I consider you a worthless hick." Honestly, he ran against the worst and least likeable candidate in history. You can go down the list of losing Democratic Presidental candidates and every one would have wiped the floor with Trump. Gore - yes, Kerry - yes, Mondale - yes, Dukakis - well....he was pretty pathetic!
2. Because of #1, middle class voters were willing to listen to anyone who would talk to them. Also, swing voters like change, and they were kinda tired of the arrogant Democrat who had been on their TV news every night for the last 8 years.
3. People are tired of the left's PC bullsh-- and their campaign of intolerance, and not just white people.
