As a website, PolitiFact is fairly transparent, but studying its work does not lead everyone to find an “obsession with fairness.” Instead, we have repeatedly found in its articles the implication of the old Stephen Colbert joke that “reality has a liberal bias,” and therefore the liberals are routinely more honest and factual than the conservatives.

A NewsBusters analysis of the first three months of this year's PolitiFact articles that evaluated a named politician or public official with a “Truth-O-Meter” ruling reveals that the site fact-checks Republicans more often than Democrats and is much harsher in its opinions of the GOP side.
