St. Petersburg Times' Truth-o-Meter is a good resource. There is so much misinformation getting propagated, especially by Republicans and other free market ideologists who want insurance companies to stay rich at the expense of America's health and productivity, and Obama shows up on the site very often. Both sides are represented, and it is interesting to see so many comments and sources evaluated side by side. Some statements are true, and some are qualified. The site does a good job going into detailed explanations of its ratings for each statement.
