Why was President Andrew Johnson's presidency riddled with problems?

Answer 1

Andrew Johnson had been vice President under Lincoln, and he became President only because of the assassination of Lincoln. Even though this was exactly what the constitution required, many people at the time felt that Johnson did not have the right to become President, and resented him. This was particularly true because Johnson was from the South. It almost seemed like a final coup d'etat by the Confederacy, for Johnson to become President.
