The US has had several bad presidents. James Buchanan was the president before the Civil War started. Ulysses Grant allowed a lot of corruption as president. Some say William Henry Harrison who caught a cold at his inauguration and died a month after taking office.

There is no objective measure of a president's effectiveness and politics plays a huge role in any attempt to compare presidents. Also times are different. Some presidents faced far more difficult situations than did other presidents. Some presidents were good with in some areas but weak with others. Some were vice presidents who replaced the elected president and some died before their term was up. However, I will say that the worst president is probably one of these : James Buchanan, Franklin Pierce, Warren Harding, John Tyler, or Andrew Johnson.
Current consensus leans towards James Buchanan for his failure to prevent the Civil War.
