Since getting a presidential nom is unlimited. is getting one like a regular nomination from a congressman,and then competing for senator so like 30 apply for 1 spot for senator but instead of presidential its 500 competing for 100 spots? would 500 be an approx number of ppl that apply for pres noms? also, on the academy website it says roughly 10,000 apply; 3,000 get noms.. since presidentials are unlimited. are the ppl with pres noms one of the 3,000?
