He also ranked low in categories like moral authority, economic management, vision/setting an agenda and public persuasion. Trump's ranking places him behind William Henry Harrison who died of pneumonia just 31 days after assuming office and John Tyler who served his last days as a member elect of the Confederate House of Representatives. Franklin Pierce, James Buchanan, and Andrew Johnson are the only presidents ranked below Trump. These men have been criticized by historians for being complicit in the Civil War and racial segregation. Obama moved up two spots to number 10, surpassing Lyndon Johnson who is remembered for his leadership in civil rights legislation and expansion of entitlement programs.Important BackgroundTrump's presidency was plagued by many scandals and crises.
