Well, after the incident in which Celestia knowingly let the Commitee of Nobles take over admin duties for a week, nopony would vote for them ever again.
@d Roy: there
was the time some of the nobles in her Commitee took power, but after a week nopony wanted to serve
them again.
@Mio: Well, Celestia let the populace choose some of the government officials. Nobles in general might get voted into office, although in modern times the Equestrian adminstration has ponies from all walks of life.
Twi would probably not be savvy enough for outright government appointment for quite a few years yet (also the whole dealing badly with stress thing), but Celestia feels comfortable letting her be a minor advisor via her Friendship letters.
And yeah, below the Sun and Moon courts, there should be 3 major administration bodies for the three races of ponies, but it's mostly a formality. Sun/Moon courts are very mixed-race, the Manehatten, Cloudsdale, and Canterlot civil administration have slight racial bias, but in general it works well enough.
