stands Barack Obama. I hope it was a total surprise, I love stuff like this. I'm also glad he's getting out in the fresh air and getting some exercise. He looks a little tired like the rest of the candidates. This whole thing started way too early. I hope he takes the time off he spoke of earlier, it's going to be a long road...
