Yep, political appointment ambassadorships tend to go to people who were major campaign contributors, no experience necessary. And yes, some of these people make really dumb mistakes that cost the US a lot. I worked as a summer intern for a political appointee ambassador, he used to saunter into the office around 11 in the morning, then go to lunch from 12:00-3:00, then come back and hang around for a few hours to follow up on whether the right kind of ice cream had been ordered for his fourth of July party. Over all, he was a nice guy--but his deputy really ran the mission. Deputies are always career diplomats, which I suppose is how we survive the political appointee system. This fellow's office was plastered with pictures of himself and the then-current president, he needed everyone to know what good friends they were...but he couldn't remember to lock the classified documents safe when he was the last person out of the office.
