I'm just curious if anyone knows how competitive SC is in regards to USMA appointments (specifically district 01!)
What makes a district competitive is not the # of people at WP but the number of outstanding candiates in that district who want to attend WP. As a general rule, competitive districts tend to be those: (1) in or near the SA involved (e.g., all of CO for USAFA), (2) where there is a major military base, (3) where many military folks retire, (4) where there is a surplus of high quality high schools, and/or (5) where the military or SAs are well known for various other reasons.
Northern VA fits the bill for at least reasons (2), (3), (4) and (5) above for WP and, for USNA, (1) as well.
Here's the rub . . . often, the more competitive a district, the harder it is to get a nom but, if you have one, the greater likelihood you'll receive an appointment. Why?
Really competitive districts typically have lots of really competitve candidates. They have MOC noms, Presidential noms, and other types of noms. Because the candidates are so competitive, lots of them end up getting appointments one way or another. Last year, for example, I believe VA-11 sent 25 people to USMA, in part b/c the MOC had 2 slots to fill (giving him 20 noms) and, as noted, lots of folks in NoVA are eligible for Pres and other noms.
Bottom line . . . you generally can't control where you live. Whether your district is competitive is a two-edged sword. You can only make yourself the best candidate possible and then see what happens.
