<p>If no other nomination is received your presidential nomination will be used for the appointment. However, admissions encourages LOA recipients to apply to all sources. If you are from a very competitive district your MOCs may not give you (your son/daughter?) another nomination since you already have what you need for an appointment. On the other hand, LOA recipients do not count against the MOCs list, so they often have nothing to lose by giving LOA recipients a nomination (LOA recipients do not need to be primary nominees, they can be listed at the bottom of the slate of 10 names that the MOC nominates)</p>
