It's no wonder that many American are terrified of immigrants. Karma's a bitch. Now defined by what they hate (abortion, gay marriage, taxes, government, etc.), it's no wonder that racist trolls have flocked to the party. And those trying to change things for the better keep hitting a roadblock of donations and wealthy interest groups.
The pressure of the frustration, fear, and hate, creates the fusion of Trump-ism. He's their most powerful bomb. The more danger he seems capable of, the better.
