I'm not sure what problem is supposed to be solved here. Sharing political opinions? I can't walk down the street without hearing someone's political opinions. That's all humans DO, is share political opinions.

The shortage is not of opinions, but attention. Why should I or anyone pay attention to your site? I can write my political opinions anywhere: Obama sucks. See? Look how easy that was.

I'm a voter. Why should I use your site? No reason.

I'm a politician. Why should I use your site? No reason.

You need to rethink. Go talk to some actual political people. No one has any reason to use your site or to give you any money. Most importantly, there's no virality factor - no one has any reason to try to get their friends to use it.

I just went to your site. It asked me something about a bike lane in Madison Wisconsin. I don't have the slightest idea what it is talking about and have never been to Madison Wisconsin. I voted no.
