Flying in the politicians for photo opportunities doesn't help either. Now it might be the case that Mr and Mrs Clinton don't get on but they could have at least got the same flight into airfield at Port-au-Prince if the photo op was that important, especially with a Médecins Sans Frontières flight had to be denied a landing slot to make way for the VIPs (these flights didn't return empty back to the US though - so I suppose that is a few hundred less mouths to feed and water in Haiti)
