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:

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?
