A while ago, I nominated a question for closure. At that time, no one else VtC'd the question. Today, someone else has VtC'd the question, so it is now showing up in the Close Queue. However, I am unable to vote on it since I have already (a long time ago).
The queue should either not show this question since I've already VtC'd it, or it should allow me to re-vote on closing it (since my original vote has long expired).
No, this is expected behavior. VtC votes age away, but you can only vote once.
Behavioral reason: it could be used to repeatedly apply a close vote over and over which would cause grief because "finally we found five people" ... bullying basically.
Technical reason: the table has a constraint on the value column ;-)
