FactCheck.org simply rocks. Are you confused about some point of order in the political campaign, or in the news? Come to FactCheck.org and see what the Annenberg Public Policy Center's fact-checking team has to say. Don't worry, these folks are non-partisan--they'll zing Kerry and moveon.org just as they'll zing Bush and Swift Vote Veterans.
Except, reading the site, you get a quick feeling that Bush & Co. must've gone into Permanent Compulsive Lying mode, because FactCheck.org finds themselves in the somewhat awkward position of correcting Bush's team and allies far more than Kerry's.
