This is not doctored and you are not likely to have seen it before. It is an actual photo taken by a person driving from Milwaukee towards Racine, Wisconsin, which for you non-Wisconsinites is a medium-sized town near the Illinois border on the way to Chicago. When he saw this, he stopped and photographed it with a digital camera.
Perhaps these creative people have something here. If these are anything like the candidates, they are full of crap!
