What is your political affiliation?
It's interesting that Political Compass thinks that nearly every political candidate is in the upper right quadrant (the exceptions being Kucinich and Gravel, naturally). Hell, even John Edwards and Barack Obama appear to be moderate conservatives, while Romney and Tancredo would be right at home in fascist parties.
For those who really do want to find out what option they might vote for, I recommend http://www.theadvocates.org/quiz.html. The questions are actually about policy, and you can easily see the direction in which your answer will push you.
