Looking at the coverage of President Obama's surprise visit to the troops in Iraq sent me on a search for similar pictures of President Bush. The contrast is striking. It could be that the troops are just happy to see the guy who wants to send them home, but I don't think that explains the reaction. After all, many of these soldiers are going to be sent to Afghanistan instead, which could be an even more dangerous assignment. It seems more likely that President Obama just inspires an outpouring of emotion wherever he travels. President Bush, on the other hand, usually got a much more restrained reception.
