You need a majority of the members to want to do it. All have to respond to the ballot. Past experience is that the members generally don’t vote even at the annual meeting.
That's because are so mind-numbingly dumb that no one is going to show up for an annual meeting unless there's actually something important to vote on.
Saying, "hey, show up and vote and you might actually get some money from it," will make people show up.
