As a response to the Top 5 Worst, I think it is only fair we look on the bright side of things:
1. Franklin D. Roosevelt- Even if he didn't fix the Depression, he fixed America's spirit, created numerous poverty safety nets, and led the U.S. through WWII.
2. Abraham Lincoln- Kept the Union together.
3. Dwight Eisenhower- Sometimes the Best Presidents are the ones that do nothing.
4. Ronald Reagan
5. Bill Clinton- Regardless of his Sleezyness, he was a good president.
