No MOC is ever going to nom based on your political affiliation, it would ruin their careers in a heart beat since they are to represent all of their constituents, not just their party.
SA Candidates would be in an uproar if they did that, and honestly Breitbart and Fox would be there in nano-seconds to cover the story. Headline Cong Issa only gives academy noms to Republicans!
What you need to concern yourself about is how competitive CA is, and it is. I believe CA is one of the states that the MOCs "talk" in other words to spread the wealth among the candidates they do not duplicate any MOC's slate. You get one nom if you are lucky.
Think about how large CA compared to MT, both have 2 Sens., and all Cong. represent the same size of population. There are going to be more applicants for CA than MT Sens. Thus, it is more competitive due to supply and demand.
The other reason that it is competitive is because they have a lot of military bases, and where there are military bases, you will have military children, statistically the % of military children going into the military is higher than the % of non-military children. They do have the Pres., but they will be like you and apply for every nom available.
Finally, Biden does not have any impact on who gets the apptmt. You submit to them they submit all of them to the SA and the SA picks that 1 candidate. The VP is like the Presidential, unlimited in the amount of noms, limited to being charge 5 at any given time. Pres is 100 per yr.
