I found this through another blogger's posting - I am such a sucker for any kind of quiz. At this website you can take a quiz to determine your liberal breed (not that I don't already know my breed, of course). (Note to BrotherR: I don't know that this quiz skews left enough for you, but give it a try!)
My Liberal Breed: Reality-Based Intellectualist
I like the sound of that...even if it does sound a little gloomy and snooty, now that I think about it. A little ivory-tower reserved. But doesn't that just go to show how freakily accurate the quiz really is?
