If they're worried about the military giving them a dog-and-pony show, the answer isn't to decline the trip but to counterpropose a more comprehensive trip than even McCain's suggesting and turn it into a real fact-finding mission. Don't spend two hours looking at charts with Petraeus. Take four or five days; go to Basra and Mosul. If they simply can't suspend campaigning for that long, send a joint team of advisors from both sides. He won't do it because he's afraid of what he might hear, which goes back to a point I've been making ever since the Jamil Hussein saga: The left would have you believe Iraq hawks can't admit that any aspect of the war might be going badly, but the opposite has always been more nearly true. For purposes of the Narrative, it's doves who can't admit that any aspect of the war might be going better, as if to acknowledge that the surge has helped to improve security or that the Iraqi army is performing better than expected lately or that plenty of Shiites are tired of Sadr's crap would be to validate neoconservatism or somehow tacitly rubber-stamp an invasion of Iran. So how about it, Barry? Break the mold. I'm sure there'll be plenty of grim news in the briefings too to help take the sting out of the reports of progress.
