... Having multiple MOC noms gives the SA more opportunities to “slot” you and thus to offer you an appointment. Let’s say Candidate A “only” has a nom from her Senator whereas Candidate B has a nom from his Senator, his Rep, and the Pres. If USNA doesn’t slot Candidate A to that Senator, she goes immediately into the national pool. If USNA doesn’t slot Candidate B to his Senator, they can still slot him to his Rep or to the Pres – two more places to fit him before sending him to the national pool. Also, MOC noms in most areas of the country are competitive and getting two [or more] shows you competed well against your peers.
