I think Trump being so disliked by women, hispanics, african American, lgbtq and arabic populations as a whole is really going to make it hard for him to win. He isnt even really liked by his own party. When the bushes, lindsey Graham, Mitt Romney and some others call him a joke, it shows how fractured the Republican party is becoming.
I think trump will do well with whites over 40, but I don't see the youth voting for him.
