Nobody should be surprised when politicians distort the facts or tell outright lies. In 2007, the St. Petersburg Times introduced a feature called PolitiFact. It's complete with a "Truth-O-Meter," and a range from "True" through "Mostly True" to "Mostly False," "False" and finally, "Pants on Fire." PolitiFact joined the Annenberg Public Policy Center's FactCheck.org. The Washington Post now has a regular feature called The Fact Checker. While such checkers promise to give voters the truth, they themselves are critiqued from the Right and the Left, accused of choosing the facts they check according to hidden agendas. Does one side lie more than the other? Do the media add to the confusion by trying to find "balance" between the two or are "facts" really what voters want to know? If so, why do they sometimes cling to beliefs in proven falsehoods?
