This isn't a nomination of liking someone, this is for intelligence level. Grav probably has more intelligence in his pinky finger than you could ever possess.

Grav = smart.

Smart = Not Unintelligent.

Not Unintelligent = Can't get nominated for the Most Unintelligent Zelaron Member.

Therefore:

Grav = Can't get nominated for the Most Unintelligent Zelaron Member.
