Tracking Promises

http://www.politifact.com/truth-o-meter/

Interesting site.  Tracks political promises and rates if they were broken or kept.  Also tracks statements for truthiness.  It is ultimately owned by The Poynter Institute.  Various warnings apply about bias, trusting a single source, and that two promises are not equal in importance.  That being said it is a pretty good site, and I particularly like the pants on fire section.
