Sadly, some MOCs do not notify candidates that they have not been selected for a nom (sorry for the double negative). IOW, the noms may be out but you may not know you weren't selected b/c the MOC failed to tell you. If you have not received any notice by now, I suggest the candidate contact the MOC's nominations coordinator and ask if the decision on noms has been made and if the noms have been submitted to the SAs. If the person answers in the affirmative, the candidate might say, "I've not received any notification. Does that mean I did not receive a nom? [or] I've not received any notification. Could you let me know my status?" If the slate has not been submitted (or decisions not yet made), you might ask if all candidates -- successful and not -- will be notified and (depending on the friendliness of the coordinator), when this notification might come.
Also, I can guarantee you that in some states and districts, it is harder to secure a nom than it is to secure an appointment in other districts and states. It's about numbers, not qualifications. There may be 200 super qualified candidates in a district in California and only 8 in the entire state of Montana. In Montana, you're guaranteed a nom and your chances are now 1 of 8 to win your slate and be appointed (maybe even higher b/c you likely have 3 noms). In CA, your chance is 1/20 just to get a nom. Then 1/10 to win your slate. So, 1 of 200. Both candidates may be super well qualified but the odds for one are certainly better.
