That would be the easiest way to do. But since the old Board just resigned over appointing a Board member that was not elected, I'm not sure if that's ideal. (Even if you actually respect the order of how many votes each candidate got, that means less if you appoint all of them.) Maybe they'll appoint the one who came third for a full term and the other two for half a term/until they can hold the next elections?
So much cake for Elections.
