The image above became one of the weekend's internet sensations. The banner pictured was hung from a building at Sioux City airport as Air Force One touched down for Obama's campaign stop.
It reads "Obama welcome to SUX – We Did Build This." You'll notice that the words "welcome to" are printed nice and small, so that a casual observer might read the message as "Obama SUX." (To put this in context, SUX is the code for Sioux City airport.)
