While the opinion is reasonable, it may not take into account that the state at issue may have numerous candidates who, if competition was national, would be competitive for an appointment, but because it is local they will not be able to compete - just a numbers game. This would arguably be unfair to the candidates from that area and so if this is the reason why there is coordination, the MOCs' approach may be a very good idea.
If the approach is used simply to spread the wealth for politics, as opposed to giving very high quality candidates an opportunity to compete, then your opinion is spot on!
