PolitiFact

The easiest verdict to read at a glance. Every check ends on the Truth-O-Meter, six steps from True down to Pants on Fire, and three editors vote on each rating, with two votes deciding it. PolitiFact began in 2007 as an election-year project, won a Pulitzer Prize for its 2008 campaign coverage and is owned by the nonprofit Poynter Institute. Corrected checks carry a "Corrections and updates" tag, which makes changes easy to find. It draws bias complaints from both left and right. One analysis that found Republicans receiving most of its False and Pants on Fire ratings also noted that PolitiFact did not explain how it chose which statements to check, and that choice is the thing to keep in mind when comparing its tallies.
