It's a senator thing, not an academy thing. You must live someplace that doesn't have as many applicants to the academy that allows them to do this. In our state, the senators communicate and "spread the wealth."
Not necessarily. It could mean that OP has something special that both senators liked and one senator liked so much he or she put OP on both slates. Our state has the same policy as yours, mom3boys: Our senators have published policies stating that they coordinate with the other so that they do not issue overlapping nominations to a candidate to the same academy. They want to spread the wealth around. There are, of course, exceptions to almost every policy.
My home state does not generate the high number of applicants that New York, California or Virginia generate, but we are a competitive state. In my state, approximately 175-200 candidates apply for senate nominations to each academy every year. Last year, DS2 applied to WP and received a nomination from our congressman. This year, DS2 reapplied to WP and applied to USNA; he received a nomination from our congressman to both academies, a nomination from our junior senator to WP, and two nominations from our senior senator to WP.
Pinkroyals32, you hit it out of the park when it came to the MOC nominations. Savor the moment. Then, come back to reality and understand that, while you are likely competitive for an appointment, it is still a zero-sum game, meaning there are a limited number of appointments available. Put simply, you are still riding the service academy application roller coaster, until the BFE comes in the mail. Good luck and may the BFE arrive on your doorstep soon!
