I the case of Bill voight and others, I feel that Mark should (and other regional leaders) should be able to nominate worthy leaders from other regions (IE. I should be able to nominate Bill, which I will until he is enshrined, and he should be able to nominate me, which I will absolutely decline at least until I have a much better showing at a couple of Nats.)
That is just because I know that any regional leader that gets chosen would probably sooner die than nominate themselves, even though they may be qualified to be in the HOF.
