The passage requirement for this is higher than the quorum because it's a proposal to change the Constitution. A law change needs 26 voters, this one needs 26 YES votes.
donsig and I have worked out a fairly elegant compromise solution. Unfortunately, I'm going out of town for the weekend and don't have the time to write up the proposal. I'll put it up on Monday if donsig doesn't put it up over the weekend.
When that one goes up I'll withdraw my petition for this one and it can be closed (it incorporates this one in a modified manner).
