What's are some open-ended questions concerning Alexander Hamilton?

I believe one of the open ended questions concerning Alexander Hamilton were his efforts to pass the Constitution and develop a sound monetary policy, Alexander Hamilton had provided invaluable service to his nation. But in this struggle, he had made powerful enemies. Demonized by the republicans as a would-be dictator or a promoter of monarchy, he saw political power slip from his grasp in 1800, when Thomas Jefferson became president and Aaron Burr vice president. Hamilton's decision to accept Burr's challenge of a duel was a last despairing attempt to stay in politics. It was an attempt that ended in tragedy.
