Sorry for the cynicism. I'd love to donate to the cause, and want to make sure I'm not giving money to a scam or (less cynically) an inefficient effort. Anywhere I can see something to convince me this page and this group is legit and making real progress?
I can say it's definitely not a scam. I have personally been to multiple meetings with organizers in Oakland and San Francisco and witnessed that it is both well organized and well staffed. To my knowledge there are over 700 volunteers across the state in every county working on this initiative. Obviously, that doesn't mean it's going to be successful. I hope you're willing to risk $5 and purchase a button or sticker so you can send in your signed petition form :)
