If you don't read Paul Krugman regularly, you should (including his blog). His cred is impressive, including a Nobel Prize in economics. However, he writes in his column for the NYT in a very accessible, and often quite humorous, manner. Here he makes a superb argument by analogy and parody. Oh, that all political discourse could prove so entertaining and enlightening! Instead, we tend to hear a lot of Tea Party rants. Am I wrong, or do some conservatives—certainly not all—go primarily with rants and taunts for political persuasion and "liberals" (hard to define, mind you) go more with humor and parody to make their points? Think The Daily Show and the Colbert Report.
