He did so many bad things I don't even know if I can list them all. Although I believe that the worst thing he did was make the spoil system, which thanks god is not in effect today. The spoils system was basically a reward for people who supported him; he hired people if they supported him or if they were part of his political party and not based on their markets. He also didn't keep most of his campaign promises, he had a short temper, and he was a gamble, and i forgot to mention that he is pro-slavery to.
