This happens all the time. As the above posters have already mentioned, most MOCs have a non-partisan panel that transfer between elected officials. And for those voted out, 'Lame Ducks' are still in office until January. My son had a unique situation. Our congressional district map was redrawn this year. We no longer even reside in the district of our current congressman. However, he is still our congressman until the new MOC is sworn in for our new district come January. I have no idea how that translates to which MOC would be charged if he were to get an appointment, but again, it's nothing new. They have it all figured out.
