Yes, I know this topic has been done three times before, but the last thread was two years ago, so I think we're due for a new one.
I love this political quiz (and others). It has its flaws, but it's pretty good, if you ask me.
It measures your political beliefs on a coordinate plane. The x (horizontal) axis measures your economic political beliefs (left-wing and right-wing; socialism and capitalism), and the y (vertical) axis measures your social political beliefs (more government control over people or less).

I also took the liberty of placing all previous active members' scores on one chart, to see how everyone compares to one another.
