If they processed your presidential nomination, that means someone should have looked at your file. First, look to see if you might have a letter posted to your portal. It may not be open if 1) you didn't submit test scores, 2) your file is on the cusp of being competitive and they are waiting to see if you submit new test scores from ACT, or 3) isn't competitive and it has been closed.
If you are going to reach out to anyone, I recommend emailing/calling your Field Force Liaison first because they should be able to give you an idea of how competitive your file is and if there is an issue, they'll call your admission rep directly.
