A nom, any flavor. Is one of the things you must have to be offered an appointment. One is not more special than any other for this purpose.
The Presidential nom is not competitive. If you are qualified for one, you get one. The competition comes in on a national level. Only 100 appointments can be charged to this nom source. There might be 600 who qualify for this nom and get it.
USNA website encourages candidates to apply for all noms for which you are eligible. For most that is 2 Senators, 1 Representative, VP and any other noms for which they are eligible. Each candidate competes against others in the same nom category.
A nom plus being fully qualified - physical /DoDMERB Q or waiver; athletic-CFA; and academic-scholastic, everything else evaluated - makes a candidate
eligible for an offer of appointment.
