As I was poking around the internet today trying to learn about who I'm going to vote for tomorrow, I found this website. You take a short survey about what political items are important to you and then it tells you which candidate most closely matches your ideology. It also tells you where you are on the spectrum of liberal/conservative.
Tip: Click on the explanations of the topics. They do a good job of explaining the topics core issues in a non-partisan way.
(By the way, it's a non-partisan nationwide website.)
