Wow - that seems amazing, especially with the LOA! The MALO information I have certainly makes it sound like if you don't get a nomination, but did all you could, that WP will find one for you. I don't know how true this is, but it will be interesting to see (well, for me! For you it's probably just stressful!).
I'm almost thinking you may not know who the nomination comes from, but may just at some point get an appointment. Sorry I don't know the timeline, but would be sure it wouldn't be until February at least when they know for sure (MOC noms are due 1/31) that you haven't gotten one from the MOC. Doesn't Sen. Hutchinson still have some that aren't accounted for? I thought people had said she usually announced about half of hers early (which are the ones you saw back in Nov here) and the other half as of 1/31. Or has her officer told you you won't get one?
Best of luck to you and I might call your RD if I were you and just make sure they're aware of where you stand on noms and try to encourage them to help you out!
