 Public Site  Developers Prototyping


VoteWise is a cross between OkCupid, Wikipedia, Facebook and Reddit but entirely dedicated to politics. If successful, it can change the face of democracy, and you can help build it. is a non-profit non-partisan website aimed at connecting voters and politicians without advertising dollars getting in the way.
