This is a nice little flash app that lets you answer some questions and then matches you to which political candidate answered the most closely to how you answered. My one beef with it is that it only goes for 100% matches. There are some questions where there were several appealing choices, so really I could go for a candidate that chose any of them.
Anyways, surprisingly, Barack Obama came out as third closest for me (due to the lack of gray support). Instead, Mike Gravel and Dennis Kucinich were closer matches.
However, the best part about this app is not their matching system. It's that if you hover your mouse over each of the questions, it will show you a quote expressing each candidate's stand on that issue. Thus this thing provides a very convenient way to do some quick research on the candidates you're considering.
