Headquartered at the Annenberg Public Policy Center of the University of Pennsylvania, FlackCheck.org offers resources that help students "recognize flaws in arguments in general and political ads in particular." At the time of this writing, with the primaries well underway in the United States, the site has excellent sections dedicated to particular candidates, including "Campaign Watches" about Jeb Bush, Donald Trump, Rick Santorum, and Rick Perry, among others. In addition, the Patterns of Deception section outlines the misleading arguments that surround debates on climate change, immigration, and gun control. For educators teaching critical political thinking, or for anyone who would like a tool for sorting through various policy debates and campaigns, FlackCheck.org is an excellent resource.
