If your MOC don't duplicate nominations they are trying to spread the wealth (very common) to give as many candidates as possible in your state/district a nomination. You only need one nomination for an appointment. I don't think anyone here can tell you your odds of getting an appointment with a Presidential nomination. Any chance you have an LOA?
Read the Nominations FAQ at the top of the Nominations Forum.
No LOA. And, unfortunately, my senators won't nominate until the end of this month (January), which I think puts me at a time disadvantage. Do most senators nominate before this time? I have seen a lot of senator nominations just on this site that were nominated way before me.
I mean, a person who was nominated by his senator on Dec. 15th and gets an offer of appointment on the 22nd got a better time advantage, and if that happens with a large amount of the candidates, my chances for an appointment go down because they would have already given out a lot already. I saw on a thread that some of those accepted had already been nominated by multiple sources getting them in on multiple nomination pools to be chosen from while I am still in only the presidential nomination pool with only 100 slots available.
