Some voters have really dumb ideas- some will never vote for someone the first time they're up for election, and some will vote against a consensus choice so that no one is elected unanimously.  What message these actions are supposed to send, I have no idea.  I'm sure some people will vote against Mo arguing that a closer shouldn't be elected.
The thing I least understand is why votes change (sometimes drastically) year to year and depending on who else is on the ballot- Shaughnessy says that next year Goose and Rice will make it because the rest of the ballot is weak, but there's no rule that you have to vote a certain number each year- why are they worthy next year if not this year?  The whole thing has become about the writers' egos, that they're somehow the gatekeepers to baseball Nirvana.  Heck, it gives them a freebie topic to write about for a couple weeks each winter.
