About Us - FactCheck.org: "We are a nonpartisan, nonprofit, 'consumer advocate' for voters that aims to reduce the level of deception and confusion in U.S. politics. We monitor the factual accuracy of what is said by major U.S. political players in the form of TV ads, debates, speeches, interviews, and news releases. Our goal is to apply the best practices of both journalism and scholarship, and to increase public knowledge and understanding." This seems to be an excellent site. They do seem balanced, and after reading it you get back to that old joke "How do you tell when a politician is lying? A: Their lips are moving." I signed up for their email updates.
