Donald Trump has insulted Latinos, immigrants, disabled people, Jews, Muslims, a federal judge and a host of others. He's run a few companies into bankruptcy. He is quick-tempered. He has no government experience. He won't release his tax returns. His views on issues change frequently. For example, he said, "I don't want to have guns in classrooms, although in some cases, teachers should have guns in classrooms, frankly" thus contradicting himself in a single sentence. He endorses bribery, saying that he contributed to candidates because, "When you give, they do whatever the hell you want them to do."
