A key part of that problem is that you can't vote against closure. Only after a question has accrued sufficient votes to close it can you start voting to open it again; it's a ratcheting flip-flop.
The ratcheting flip-flop is the best-case scenario for when a question is popular enough for some people to stick around and keep it open. Most of the time, closure is a death warrant for a question. I've seen some real "diamonds in the rough" closed because of this.
But it appears Jeff is oddly against this issue:
