If it helps.... I did not receive a USAFA nom during the initial round, but I still applied. As the school year came to a close, I was on the national wait list and after someone dropped out (very late in the game), my Senator's office was called by USAFA admissions and was asked to nominate me because I was the next highest qualified on NWL to backfill the slot from the student on his slate that backed out. In the final weeks prior to BCT, there is a frantic race to fill all available slots and they move quickly. If the school wants you, they fill help find a NOM on your behalf. The key is that you did apply to all nominating authorities and you did complete the admissions process.
