Bush is not a bad person, in fact he is perhaps the best person to ever be a President.
Problem is we shouldn't be talking as Bush the man but rather Bush as a President.
Bush allowed for obama to be elected, and for supremacy of Liberal thought that we see today. He done this due to his inability to speak well and defend Conservative ideas. Though out his Presidency he believed that right will triumph over lies, without understand that Politics is all about well phrase lie. If you can not defend in the media your ideas your opponent will destroy them.
He continued to ignore the Press attacks, allowing them to build the pervasive myth that is Bush today (worse Economy, not responding to Katrina etc..).
