for this to be remotely useful and interesting, you do need some critical mass of people interested in discussing these topics. i'm sure you've thought of these already, but if i were you'd, i'd ping every legislator i could about the site and what it's trying to offer - potentially get them to start dialogues with their constituents through it or something. i'd also reach out interest and lobbying groups(on both sides - e.g., repeal Prop X, support Prop Y) - it's all about just building the presence. one argument against those is that you'd want to get "real people" discussing the issues, but i think you'd at least get some impassioned perspectives from these people, who are the ones that arguably care the most - from there, you can hope it builds on itself in facilitating a dialogue.

to the earlier comments, the site probably needs a design refresh and some tangible, clear focus where visitors can engage (not currently clear)
