I voted to close a question, then realized it was not the best fit. So I went to change my vote, and saw there was no option to do this:
Not a big deal, I thought. I can retract (seeing as that's my only option really) and then re-vote to close.
But! It apparently is not meant to work that way, as I am met with this when I try to recast a new vote for the reason I wanted:
My initial thought was wait a minute, but that did not help.
Looking through Meta, it appears this has come up before: although the answer is not very definitive on why this occurs.
Votes can only be undone when the post is edited. If your vote really was accidental, you can resort to editing the post and then changing the vote.
And this has been the tone of a few similar question, be careful next time or edit the question.
Is this a bug, and oversight, or is there something I am not getting here?
As an update, editing the question did not allow me to recast a vote!
And, after @NHinkle answered below, why is this not possible and can it be added?
