It's farcical. It's just circlejerking. The idea that advertising pro-prop19 to Reddit would have made any sense in the first place is just ridiculous given that they're all pretty much uniformly in favor of it.
It's fun to watch them run around being outraged boycotting and generally wasting their own time though.
It's an important way to maintain voter awareness and actually motivate them to vote when they get the chance. In politics, it's often more important to advertise directly to your base than anywhere else.
Nice hack, reddit.
