Obama being Obama?

Obama states that he will head to Iraq when the primary is over. He's been challenged by McCain to do so and it is to his credit that he allowed McCain to get him to go. Why? Because most politicians would and will do exactly the opposite of what their opponents challenge them to do. I haven't seen the video but the humility that he displayed in the beginning might be making a comeback. Not sure that can last, though. There is going to be whithering fire on both sides and politicians become, well, politicians when getting battered.
