Matt Drudge has a ton of details about President Bush's secret trip to Baghdad. I think it's pretty cool, although my earlier prediction was that he wouldn't travel to Iraq until next summer as part of his presidential campaign. This was far better, however, and shows an astonishing level of concern for our troops in the region.
Some may say it was a political stunt, but I think the initial secrecy of the trip works against that. If Bush were going just to score political points, he'd want the trip to be more high-profile and better timed in the campaign cycle. I still think he will go again next summer, but this trip was probably not primarily motivated by politics.
