No one honestly thought this debate would change anything. McCain tried to alter/better his approach, yet couldn't reinvent himself and manage this. Obama was poised and presidential, as a good portion of the world outside of the USA desires towards the reality of the one world economy we have been dealing in for years now.
I know it's not for the "rest of the world to decide" yet as blind as we choose to be, the influence is there and not going away. We have not been isolated for a long time, and are fooling ourselves if we believe we can act like it.
When citizens think with their brains and not clouded by emotion (fear, which is always based in ignorance) we will select the between the two choices to the betterment of our and the world's future.
