The blog "Semantic Compositions" has been critically reviewing Lakoff's political writings in a delightfully sane and fun way:
Part I: What George Lakoff knows about the mind
Part II: How not to test a hypothesis
Part III: Excellent, excellent
Part IV: Relax? I can't relax!
All of them are good, especially the last one, which is excellent. The series isn't done yet; there's a Part V that I'll try to remember to put up when it comes out.
UPDATE (10/18): And Part V is out:
Part V: Elephants in George's Pajamas
