Originally I thought the McCain ad was dishonest simply because it ignored the Pentagon's request that Obama not visit the troops; I assumed that cameras would have gone along but I didn't find that to be any kind of crux of the matter. MSNBC, of all places, sets me right:

NBC's Andrea Mitchell reports that there was never a plan for Obama to take the press to Landstuhl, despite the claim by McCain folks and others. The plan was to go with his military aide, retired General Scott Gration. The Pentagon said Gration was off-limits because he had joined the campaign -- violating rules that it not be a political stop.

Obama had gone to see wounded troops in Iraq earlier in the week, without even confirming he'd been there. No press, no pictures. He has done the same when he goes to Walter Reed -- never any press.

McCain is a desperate, desperate jackass.
