I Side With is a Q&A site that asks you several questions about the political issues of the day and how important they are to you. The quiz took me a few minutes for me to answer, then the system takes a minute to analyze your responses. It then displays all the candidates you are closest to (who you side with!) from several parties, where you stand on the issues, your ideology, the larger groupings or themes of the issues, and where other voters in the country think like you. Very interesting.
It show your relation to all the candidates and on what issues.
