StudentInWisconsin- I'm pretty sure I didn't get his principle nomination, because I already had an LOA, and if you have an LOA and you're just on the congressman's slate, than you're automatically in, so generally they wouldn't waste a principle nomination on you.
I'm not sure about your chances, if you have two nominations I assume they are pretty decent, but I don't know a lot about that. Just don't give up hope, from what I've heard a majority of the appointments have not been given out yet. Good luck!
