After I read your last post, my first reaction was to want to tell you "of course, politics don't play a role in selecting students for CRNA school." Unfortunately, after about a millisecond of thought, I had to admit you could be right. For example, if an important physician, particularly a surgeon, practicing in the same area as the school has a favorite candidate, that person has a definite leg up on the competition. I've seen that at more than one program.
Hang in there. One thought might be for you to contact the program directors at the schools
where you have applied and ask;
1. Why you were not accepted.
2. What you can do to make yourself a stronger candidate.
I know that the director at Newman University will happily answer these questions. If the candidates apply in following years, he looks at whether they have accomplished the things he recommended. If they have, they are given higher consideration when re-applying.
