Not like what? Rolling or submitting their slate until January? Hate to tell you, but they are both. No MOC that I know of does a rolling nom. If you look at NJ nom threads you will see they typically drop their slate late.
Also Booker is unique since he was a special election. Last year he and Chiesa split their slate with both noming 5 of the 10. This will be his first full slate.
Every MOC will be briefed by the SA office located in the Pentagon. This office will tell them how many charges they have available to them for this years group. They will be informed of what they must adhere to legally regarding the process. This occurs in July. It maybe because this will be Bookers first slate they are waiting for the briefing before adding this to their constituents page.
~~~ As I said before the MOCs do not have to submit their slate until the end of January. There is more than enough time for them to get the application on their web page.
Also every MOC has a different system. Our DS found out his 3 noms from the NC MOCs at 3 different times, even though they all had the same deadline for applications.(9/30)
~ Sen Dole ----Thanksgiving. No interview. Letter sent
~ Sen. Burr ---- January 15th, interviewed Jan 9th. Letter sent
~ Cong. Butterfield ---- January 31st. No interview. AFA portal. Letter sent Feb.
Applying to an SA is a marathon, not a sprint. Be prepared to not know if you have an MOC nom until Thanksgiving at the earliest .
