No offense to anyone putting Obama, but I don't think it is quite possible to call him the worst President after 6 months.

Jimmy Carter was a poor President in my opinion as well because of his micromanaging style which many people say is similar to that of what Obama is currently doing.

I don't like George W. Bush that much, but it is difficult to judge his career as of yet.

I would personally say that Warren G. Harding is one of the biggest failures in US History. With his corrupt administration, and scandals surrounding him he could be seen as one of the biggest failures as a President.
