I just took a quick look. It only takes $5.00 filing fee to start and initiative. While I am sure the cost would go up drastically if you proceeded with one, it might be worth it to file one to allow gambling in certain locations in Washington state. If a person could actually get it on to the ballot, I would think the tribes would have to respond. Hitting them in the pocket book may be the best way to get their attention. I think at least 17 million was spent in the fight to defeat the GMO initiative.
