Aurvandil was an incredibly repressive tyranny. As I said several times, their entire realm was designed to focus all power on the ruler. The elections were a sham. The whole "we don't campaign" crap was intended to make sure that only cronies of the ruler (I.e. he and his multies/friends) got elected. Except for banker, and who cares?
When that kind of power structure disappears, I can understand how it would take a while for the realm to recover, and all the kinks to shake out.
