When you tell demographics that comprise over half the US population that they are basically second class citizens, and in fact you'd like to get rid of them for a new set of darker and recently immigrated faces, it tends to not go over so well.
Or when you spend more time getting refugees from countries hostile to us and our values, and then give them a boat load of welfare bennies. Or when you are more concerned about getting hairy apes into little girls shower rooms than you are trying to create the conditions for decent job opportunities, to name a couple of examples.
The Orange Ass Clown wasn't even a great candidate, and they still got wiped. And they will continue to have no clue.
