WorldNetDaily -- the far-right web site that even some conservatives say peddles "paranoid conspiracy theories" -- is now touting a book that purports to demonstrate that liberalism is a mental disorder:

WND goes on to assert: “Rossiter explains with great clarity why the kind of liberalism being displayed by Barack Obama can only be understood as a psychological disorder.”

Given WND's track record, I can only assume WND is engaging in a Rovian effort to accuse their counterparts of their own shortcomings.
