Presidential Candidate Quiz. USA Today has a good quiz for "choose your presidential candidate". They allow you to change the weights on the various issues, and it shows you, in real time, how well the candidates are doing in your ranking as you proceed with the questions.

My favorites according to the Quiz?

Romney, Brownback, and Thompson. Biden and Edwards were my lowest.

Romney being the top shows a problem with quizzes, though. I don't believe he really holds those positions. He was a liberal governor of Massachusetts, and it was amazing that he got the endorsement of so many conservatives.
