Bush is one of the worst presidents of modern time and one of the most divisive for his actions.

In 2012, a Gallup poll found:
10% said Obama was outstanding, G.W. Bush 7%
28% said Obama was above average, G.W. Bush 18%
26% said Obama was average, 28% said Bush
17% said Obama was below average, 22% said Bush
18% said Obama was poor, 25% said Bush.
Now I know this is a highly partisan issue but from above examples it can be found that many consider G.W. Bush a worse president than Obama and some have even named Bush as the 2nd worst in modern history.
