Why does everyone call George Bush the worst president?

Wow, what list did you see ?Jackson is no where near the worst on any list I have ever seen.I think you may be referring to Andrew Johnson ,who was the only other President to be impeached, besides Clinton. I think you know where Clinton will end up on that list. Most list Buchanon as the worst. It is far too early to judge Bush's presidency. There are so many things that could happen in the near future to effect how he is viewed in historical terms. History will define his Presidency, not nay sayers who do not agree with his policies now.
