> Point taken, but I believe when Obama did it, there was already someone appointed to take the outgoing ambassadors place immediately (at least, here, it was the case).
Unless I'm misremembering, that wasn't the case. Obama was appointing ambassadors regularly for a few months.
Not an appointee, but it's worth noting that there is a deputy chief of mission at every diplomatic post. This person is always a career diplomat with extensive experience, and is in place for precisely this reason. To take over and run the mission until a politically appointed ambassador is present.
