Expanding Medicare, and no child left behind should both be praised as legitimate progressive actions. Along with the fact it's a hard hard job to be commander in chief after 9/11-I can appreciate that it was not at all easy.
However post 9/11 GWB seemed to be overwhelmed. The initial stages of Afghanistan were badly thought out-the failure to get Bin Laden, putting Karzhai in charge and then forgetting about it until '06 was a bad decision. The Afghanistan strategy was one that could have worked at first-it was just poorly managed.
However the entire war on terror was awful, Ironic I know coming from a guy call Blair. Stripping soldiers of their human rights under the Geneva convention is awful, no matter how you look at it. Then torturing them, and keeping them without trial is even worse. I'm sure someone will claim 'oh yeah we got information'
There's shaky evidence of that I also don't think that it can be defended morally at all, when the US prides itself on being opposed to that.
His reaction to Katrina as well makes him one of the worst post war presidents-appointing your friends to key positions often happens in politics, but appointing stupid friends with no experience, and pulling money of the FEMA is not good
