From wiki:
David Mikkelson, the creator of the site, has said that the site receives more complaints of liberal bias than conservative bias,
[23] but insists that the same debunking standards are applied to all political urban legends. In 2012,
FactCheck.org reviewed a sample of Snopes' responses to political rumors regarding
George W. Bush,
Sarah Palin, and
Barack Obama, and found them to be free from bias in all cases. FactCheck noted that Barbara Mikkelson was a Canadian citizen (and thus unable to vote in US elections) and David Mikkelson was an independent who was once registered as a Republican. "You'd be hard-pressed to find two more apolitical people," David Mikkelson told them.
[23][24] In 2012,
The Florida Times-Union reported that
About.com's urban legends researcher found a "consistent effort to provide even-handed analyses" and that Snopes' cited sources and numerous reputable analyses of its content confirm its accuracy.
