Why do I have to sign up to use it at all? You want people to get involved in the process but you add friction. My guess is, your bounce rate is high.

I'm sure there are plenty of features that require an account - but I'd imagine there are still ways of displaying and sharing the public information you've gathered within your tool without getting people to give you their e-mail address and generate yet another password.

Just think about it - the landing page should say something like "check the voting record of your senator against what you believe in. click your state." - and then show a map.

With this - you'd at least get ONE click. My guess is now, you miss out a lot because you want people to buy into what you're building without providing ANY value other than "feel good to change government" which as we all know isn't enough to get people to care.
