Over at About.com, Political Humor editor Daniel Kurtzman maintains one of the web's most comprehensive collections of political jokes, cartoons and images. (Full disclosure: some are them are from Perrspectives.) Now, he has come out with a fun-loving how-to book for liberals, "How to Win a Fight with a Conservative."
In addition to his new book, Kurtzman has also put together a quiz to help you determine what type of liberal you are. His very short (and very fun) political SAT is part aptitude assessment and part Rorshach test. My own liberal diagnosis: "social justice crusader."
Visit the site for more on the book, the quiz and helpful liberal links and resources.
