Probably the worst president in nearly a century and a half. Led us into two failed, costly and pointless wars that disgraced America's global reputation, grossly violated the Geneva Conventions through torture, set up a massive Orwellian surveillance apparatus, was totally incompetent and lost control of his administration to the empire-building neocon lunatics be surrounded himself with, pandered to the Religious Right like no other president, implemented voodoo economics and presided over the largest financial crisis since the Great Depression. Easy 1 star.
You think he was worse then Hoover
Certainly.
At least Hoover worked his way up to become President.
