The worst president in history? That is highly opinionated; as some say Andrew Johnson, yet he helped the South when the radical republicans wanted to take our land. Another low rated one is Warren Harding; he encouraged industrialization and a strong economy independent of foreign influence. The some say he did more good than harm, with the
Teapot Dome Scandal but was blamed for, yet he did good things as well. Richard Nixon accomplished much, good and bad, depending on how much his term in office helped, or hurt you. The beloved Abraham Lincoln is hated by many in the South, even today.
I think George Bush was a terrible president! Then I hate interventionism. AS for Barack Obama, he seems like a chameleon, always able to change with the situation, and being such, may well be the least moral president yet!
