For those that still don't think that GW will be remembered as one of the worst presidents of the USA, here is just a very small example of how he was seen worldwide. If someone will miss Little George that will be the advertising industry, specially those working in the creative departments. I don't think any other American president has given them so much material to work with!
Bush was clearly the poster boy for what is the bad side of America. Obama so far is the poster boy of hope.
If anything else, Obama has already delivered a change, that change being the general image of the US.
Welcome change, welcome hope!
